S411-S428 Conductivity probes
For industrial applications
Specially designed for use in an industrial environment, these make it possible
to cover a very wide measuring range, thanks to versions with temperature
sensor, special versions with PVC, PTFE, PVDF body, graphite, steel or platinum
electrodes. Conductivity is measured by submerging the two metal electrodes
of the probe in the solution to be measured. The passage of current between
the two probes allows the electrical resistance of the liquid and therefore its
conductivity to be measured. The measurement is influenced by the
temperature. In saline solutions, there are variations of 2% / °C. This variation
can reach 7% / °C, therefore the use conductivity probes with no temperature
sensor is preferable if the solution being examined remains at a temperature
of between 15 °C and 25 °C.

The S410/IND series of inductive sensors has been engineered and
developed to produce an electrode that is very powerful but at the
same time competitive. The result has been obtained by moulding the
sensor made using polypropylene reinforced with fibreglass.
This sensor offers all the advantages of the inductive cond.
measurement method, including the absence of passivation of the
conventional conductivity electrodes. All the sensors in the S410/IND
range are temperature-compensated, and are also designed for inline, submersion or tank installation.

S423/OXYSENS™
Main measuring range
The oxygen contained in the liquids is measured using the so-called Clark cell system. These cells generate a
current proportional to the partial pressure of the oxygen, which can be detected using a suitable signal converter.
In order to prevent interference during measuring, the Clark cell is protected by a gas-permeable membrane. The
membranes typically used are made from PTFE but, as this material is mechanically fragile, frequent changing is
often necessary, along with the related “demanding” operations (interruption of measurement, replacement of the
electrolyte, regeneration of the electrodes). The S423 solves this problem by using a membrane made from
OPTIFLOW™. Manufactured as a sheet around a layer of steel, it is very stable mechanically and very resistant
to chemically aggressive environments as well as high pressure. Thanks to the special construction of the
measuring electrodes, this system also makes the sensor totally “maintenance-free”.
Maintenance
OXYSENS™ sensors are maintenance-free, and do not require the replacement of the membrane, electrolyte or
regeneration of the electrodes, to measure the oxygen in aqueous samples. Typical applications include water
treatment plants and the fish industry.

S411-S428 Conductivity probes
Specially designed for use in an industrial environment, these make it possible
to cover a very wide measuring range, thanks to versions with temperature
sensor, special versions with PVC, PTFE, PVDF body, graphite, steel or platinum
electrodes. Conductivity is measured by submerging the two metal electrodes
of the probe in the solution to be measured. The passage of current between
the two probes allows the electrical resistance of the liquid and therefore its
conductivity to be measured. The measurement is influenced by the
temperature. In saline solutions, there are variations of 2% / °C. This variation
can reach 7% / C, therefore the use conductivity probes with no temperature
sensor is preferable if the solution being examined remains at a temperature
of between 15 °C and 25 °C.

The S410/IND series of inductive sensors has been engineered and
developed to produce an electrode that is very powerful but at the
same time competitive. The result has been obtained by moulding the
sensor made using polypropylene reinforced with fibreglass.
This sensor offers all the advantages of the inductive cond.
measurement method, including the absence of passivation of the
conventional conductivity electrodes. All the sensors in the S410/IND
range are temperature-compensated, and are also designed for inline, submersion or tank installation.

S423/OXYSENS™
Main measuring range
The oxygen contained in the liquids is measured using the so-called Clark cell system. These cells generate a
current proportional to the partial pressure of the oxygen, which can be detected using a suitable signal
converter. In order to prevent interference during measuring, the Clark cell is protected by a gas-permeable
membrane. The membranes typically used are made from PTFE but, as this material is mechanically fragile,
frequent changing is often necessary, along with the related “demanding” operations (interruption of
measurement, replacement of the electrolyte, regeneration of the electrodes). The S423 solves this problem by
using a membrane made from OPTIFLOW™. Manufactured as a sheet around a layer of steel, it is very stable
mechanically and very resistant to chemically aggressive environments as well as high pressure. Thanks to the
special construction of the measuring electrodes, this system also makes the sensor totally “maintenance free”.
Maintenance
OXYSENS™ sensors are maintenance-free, and do not require the replacement of the membrane, electrolyte or
regeneration of the electrodes, to measure the oxygen in aqueous samples. Typical applications include water
treatment plants and the fish industry.

Optical technology
The S432/C/OPT sensor measures oxygen with a built-in temperature probe. The measuring technique is
based on the optical principle: a diode emits a light blue towards a support on which a fluorescent substrate is
applied. The substrate initially reacts by emitting a red light (luminescence), then returns to its initial state. The
intensity of the red light produced and the rate of return to the initial state are related to the concentration of
oxygen present. This innovative method ensures reliable, accurate measurements with no drift over time,
therefore system calibration is no longer necessary. No maintenance is required except for replacing the
luminescent support about every two years. The system does not consume oxygen, therefore it is suitable for
the most varied fields of application, including those in which the measuring liquid is almost stationary.
Digital technology
Built-in pre-amplification circuit and digital signal processing. The S432/C/OPT sensor saves the calibration
data for optimal data management. The output signal is provided on the RS 485 serial port.

S462 Turbidimetric cells
S462 turbidimetric flow-through measuring cells. The measuring
principle is the deviation of light produced by the particles
suspended in the liquid. Thanks to the dual sensor system, turbidity
can be measured at low and very low concentrations with high
levels of precision and repeatability. The absence of contact with
the measuring liquid and the optical LED technology make the
system stable over time and minimise the need for re-calibrations.
The cell can be installed directly in-line. The maximum allowable
pressure is 6 bar, or on bypass piping. The flow rate does not affect
the measurement.
Applications
• Water treatment plants, on leaving the filtration or decantation
sections.
• Waste water refining plants for agricultural or industrial reuse.
• Food industry, in particular in the production of beverages,
wine, beer etc.
• Swimming pools water.

Measurement
and Control
Measuring the OUR
To control the efficiency of a biological activated sludge
treatment plant, the test for determining the Oxygen Uptake
Rate is performed on a sample taken directly from the
oxidation/nitrification basin. The classic method involves
recording the consumption of oxygen dissolved a sample of
activated sludge, with known MLSS concentration and volume,
previously brought to rapid saturation with a forced ventilation
system and kept constantly mixing, at regular intervals.
Mixer
Probe thermo-compensated
Air insufflation
system
The time/concentration of oxygen pairs are then turned into a
graph, and a descending, almost straight curve is obtained,
whose slope represents the rate of consumption of oxygen by
the biomass (see figure 2). The OUR value obtained in this
way is generally expressed as mg O2/g SSV*h.

Use
Biological activity test
Checking the degree of activity of the biomass in breaking down a

Assessment of the degree of inhibition
Determining the possible toxic effect of sewage containing potentially
inhibitory substances by making use of the OUR test
Biodegradability test on special waste water
Testing the behaviour of the activated sludge when fed with a
compound, the effect of whose biomass is not known for certain. For
example the acceptance of special waste water at the treatment plant.
Characterisation of organic substrates
Quantification of the organic substrate present in influent waste water,
in order to determine the fraction of readily biodegradable COD of
waste water for the integration of a carbonaceous substrate in a state
of denitrification or biological dephosphating.

4001 series
The photometric method
In recent decades, photometry has developed as an essential means of
analysis because it enables the “quantitative” determination of both organic
and inorganic compounds.
The technique uses the colorimetric methods characteristic of certain analytes,
i.e. the properties of certain chemical reagents to develop colour with an
intensity proportional to the concentration of a given substance, at a
particular wavelength of the spectrum visible between the UV and IR (from
400 to 800 nm).
Compared to UV or IR spectrophotometry, the colorimetric technique has the
tremendous advantage of relying on well-defined linear reactions with few
well-known interfering substances.
The Palin method employs the interactive DPD principle to determine the concentration of certain oxidants such as: free
chlorine, total chlorine, chlorine dioxide, ozone, peracetic acid, bromine, permanganate etc.
The DPD reacts with the oxidant present in the water, almost instantly producing a pink colour, making sure that all
those factors that may affect measurement (pH, μS, °C, organic matter etc.) have no influence on the analytical
methodology.
The phases of the 4001 measuring cycle are:
• Entry of the sample in the measuring cell for
washing/priming
• First measurement on the sample as is
( photometric zero )
• Reagents introduced via peristaltic pump
• Development of the reaction through stirring
• Reading of the colour ( absorbance ):
The differential measurement between the zero
and the absorbance is processed by the
electronic processor and converted into a
concentration value, using specific correlation
tables developed in our laboratories.
The electronic controller displays the substance
measured in mg/l and decides whether or not to
activate the dosing components designed to
control or correct it.
The running and maintenance costs are very low
and, especially, system calibration takes place
automatically at each measuring cycle.
Industrial applications include the analysis of
drinking and waste water as well as the analysis
of food products, pharmaceuticals, chemicals etc.

Automatic linearization stored in the analyzer is used to compensate the nonlinearity of the Beer-Lambert law for high concentrations.The measurement is the
weighted sum of the concentrations of NO2 and NO3, although, in most
applications, the concentration of NO2 is negligible compared to that of NO3.

The measuring principle is based on the UV absorption of ammonia in the NH3 gas
phase. The addition of a small amount of sodium hydroxide (NaOH) to the sample
allows the almost complete passage (stripping) of the ammonium ion NH4+ to the
NH3 gaseous form.
An FFT (Fast Fourier Transform) algorithm is applied to the spectrometer to extract
the absorption signal typical of ammonia gas. This method is very selective as no
interferent is entrained for determination on surface water or waste water.
Turbidity or the colour of the sample do not influence the measurement, as the
determination is made on the gas phase. Waste water with suspended solids (active
sludge in an oxidation tank) can be determined
without prior filtration, thanks to the size of the sample inlet pipe.
The automatic washing system ensures continuous system cleaning. The stability of
the measurement (unlike the electrode system) eliminates the need for expensive
calibration solutions. A zeroing cycle takes place for each determination.

Filtration system for analysers
Analysers
The SF-100 iltration system, often used upstream of
online analysis systems, is a self-cleaning ilter that
uses compressed air with a programmable
frequency to keep the stainless steel ilter element
clean.
While most of the liquid in analysis passes very
quickly passes through the polypropylene body of
the ilter, only the amount necessary for the analyser
is iltered through the stainless steel ilter element
with a special proile. This prevents a rapid
accumulation of dirt and deposits on the ilter
element.
In addition to this, the iltration system uses an
electronic timer which periodically, at an interval
programmable by the user, opens the NC position
on the three-way solenoid valve, allowing the entry
of compressed air at a suitable pressure that
enables powerful counter-current washing of the
ilter element.
This backwashing proves quite effective in removing
solid particles trapped on the outer surface of the
ilter element.
The frequency and duration of the automatic
washing cycle can be programmed by the user in a
wide range of values.

Electromagnetic
induction low meters
An electromagnetic flow meter consists of a sensor and a transmitter. The flow meter is used to measure the volumetric flow rate of
conductive fluids and waste water. The measurement is independent of the density, viscosity, temperature and pressure. The conductivity
of the fluid must be greater than 5μS/cm. The measuring instrument must not be crossed by fluids carrying solid bodies of high
dimension that cannot be considered suspended solids. Head losses are absent and straight stretches reduced upstream and downstream
of the instrument are necessary. Several types of output signal are available. The main applications are in the following sectors: chemical
industry, energy sector (generation and distribution), mining, water treatment, paper industry, pharmaceutical industry, food industry
and environmental protection.
Measuring principle
All electromagnetic flow meters operate
according to Faraday's law.
Um = K x B x V x D
Um – Induced voltage measured between the
two electrodes.
K – Correction factor of the sensor.
B – Magnetic induction.
V – Velocity of the fluid.
D – Internal diameter of the measuring pipe.
The passage of the conductive liquid through the
induced magnetic field generates an induced
voltage that is exploited to measure the flow
rate. The magnetic field produced by the coils
traversed by current passes through the
measuring pipe and the fluid passing through it.
This generates a voltage in the fluid that is
proportional to the velocity of the fluid. The
voltage is measured by means of two electrodes.
Flow rates
Installation
The meter is able to automatically recognise the direction of flow. The forward direction is set at the factory and is
indicated by an arrow on the instrument. If possible, install so that the flow direction is the same as that stated on the
label. In order to ensure the accuracy of the measurement, upstream of the instrument, there should be a straight section
of piping of equal diameter and a length of at least 3 times the diameter of the measuring pipe. The length of the straight
pipe downstream of the sensor must be greater than twice the diameter of the measuring pipe. (Fig. 1)
Installation position
The electromagnetic meter must be installed so that the
pipe is always completely filled with fluid. In the case of a
half-empty pipe, the meter must be installed in an
underground channel, or in a “gooseneck”, to achieve a
siphon effect. (Fig. 2)
Fig.1 - Requirements for installation on straight pipe
Installation may be vertical or horizontal but in the latter
case, ensure that there is no deposit of material on the
electrodes. (Fig. 3)
Installation must take place in such a position that the
piping cannot be emptied. (Fig. 4)

S100F
Ultrasonic “transit time” meters
The 100F low measurement system is composed of a digital
converter for wall installation and two ultrasonic clamp-on or
insertion transducers. The transit time of a luid inside a pipe with
a cylindrical section is the operating principle on which the
instrument is based to calculate the value of the instantaneous low
rate.
DSP, Digital Signal Processing, technology ensures low sensitivity of
the system to any potential disturbing factors. The dimensions of
the pipe may vary from 20 to 4000 mm (by using different
transducers) while liquids can be:
ultra-pure, drinking water, chemicals, dirty water, cooling water,
river water etc. As the transducers are applied externally to the
pipe, are not in contact with the liquid and have no moving parts,
the transmitter will not be damaged by wear, deposits or pressure.
All the coniguration values entered by the user are saved in the
EEPROM, which is password-protected to prevent accidental
changes. The transmitter is equipped with a clock to save the date
and time of the measurement, and is battery-operated.
In the event of a power failure, it will therefore be necessary to
reset the (time) values lost. In the event of incorrect setting of the
totaliser, the other functions are not compromised.

DFM-5.0
“Doppler” effect low meter
The DFM-5.0 effect low transmitter is suitable for most liquids, such as
water, waste water, chemical liquids, sludge and viscous liquids. It
controls, indicates, totalises and transmits the low rate in gallons, litres
or other units of measurement. The sensor is mounted on the outside of
a pipe made of metal or plastic.
To measure the low rate, the acoustic pulses, generated by the sensor,
are relected by the particles or gas bubbles, present in the liquid, and
are sent back to the sensor. Installation can be done without stopping
the plant. There is no contact between the sensitive element and the
luid whose low rate is to be measured and no cutting or drilling are
required on the pipe. The sensor is a parallelepiped shape, is not
affected by dirt or deposits and is easy to mount on the outside of a
pipe using a tape. Easy programming using 3 program buttons.
Through the menu, it is possible to select the diameter of the pipe,
engineering units (gallons, litres etc.) and the totalisation velocity and
deine the set of relays, the sensitivity and the damping. Totalisation
and calibration data is password-protected and also protected against
power failures. DFM-5.0 is recommended for liquids containing solids
or air bubbles, for steel, iron, PVC and ABS piping.
The sensor transmits high frequency sounds in the liquid, through the wall of the
pipe. The pulses are relected and sent back to the sensor from the solid particles
and air bubbles present in the luid. Because of the movement of the luid, the
relected sounds return to the sensor with an altered frequency (Doppler effect).
DFM-5.0 continuously measures the deviation of the frequency in order ensure
very precise measurement of the velocity of the luid and, therefore, the low rate.

Operating principle
PDFM-5.0
The PDFM-5.0 Doppler effect low meter is suitable for monitoring a low rate or
for identifying problems encountered in a closed pipe. It is an ideal instrument for
evaluating the performance of low meters inserted in line. It can be installed,
calibrated and operated in a few minutes and then used as a temporary
replacement for an in-line transmitter.
Easy to transport
Each PDFM-5.0 unit comes with a convenient and stylish carrying case, the sensor, and
a stainless steel installation kit. The unit can be used for a short time or left in a position
to transmit and/or record data.
Energy for a full day
In the absence of voltage, PDFM-5.0 can operate continuously (with 4 to 20 mA and
RS232 active) for one day using the internal rechargeable battery. A warning light
indicates that the battery charge is low.
Easy setup and calibration
The sensor can be installed and calibrating in just a few minutes. Place the paste
(supplied with the instrument) on one face of the sensor and afix the latter to any pipe
over 1” (25 mm). Use the three keys on the instrument to enter the pipe diameter and
engineering data required. PDFM-5.0 begins to indicate and transmit the low rate
value immediately.

AVFM-II
“Area x Velocity” low meter
The system simultaneously measures the level and the velocity of the luid in order
to calculate the low rate in an open channel or in a pipe.
Recommended conditions of the channel
The best precision is obtained if the low is
distributed evenly, rather than turbulent. The
channel, immediately upstream of the sensor,
should not have abrupt changes in the level of the
bottom. The slope of the channel or the pipe must
not be greater than 3%. The low must not have excessive turbulence and the velocity
on the sensor should be less than 1 m/sec. The conditions downstream of the sensor
do not affect the measurement if the proile of the surface is not changed just above
the sensor itself.
Tolerance for dificult low conditions
The system can measure velocity of up to 6 m/sec. To ensure maximum precision,
electronics and software have been developed to compensate for the high and low
values, due to turbulence. The standard level/velocity sensor can measure the low
rate in pipes that are partially or totally full up to a pressure of 0.65 bar. No
adjustment is required.
Conigurations with alternative sensors
The standard sensor, submerged, is unique for its two measurements, level and velocity. It is installed with a set of screws on the bottom of the
pipe or channel, or inserted into the bracket supplied with the instrument. Other models of sensors are available for special applications, for
example an ultrasonic level sensor with a small measuring range and a submerged velocity transmitter for measurements in a manhole. The
sensor cable can reach 150 m.
No calculation - No programming code
To calibrate the AVFM-II, simply enter the pipe diameter or width of the channel and select the unit of measurement from the menu. The low
rate, level and velocity can be expressed in gallons, litres, ft³ or m³. The calibration parameters remain stored in the event of a power failure.

STINGRAY
STINGRAY Portable “area x velocity” low meter
This new portable instrument works powered by alkaline batteries for a very long
period of time and stores measurements of the level, velocity and temperature of
the water in open channels and in partially illed or pressurised pipes without the
need for constrictions or weirs.
STINGRAY uses a submersible ultrasonic sensor
for continuous monitoring of both the velocity
and the level of the channel or pipe. The sensor
has no moving parts and is resistant to dirt and
corrosion.
It includes the instrument, the sensor with a 7.6 m
cable, an accessory for installing the sensor, batteries and software.
No calibration is required. On the front there is a bar showing the velocity, level,
temperature, battery charge and inally the memory used/available. The display
turns off automatically after 60 seconds to save power.
The software makes it possible to set sampling intervals, to download the iles
and to get an indication of the variables.
Flow rates
The logger displays the iles and the velocity calculated trends in trend graphs and
tables, including the minimum and maximum values, the average low rate and
total low rate in the normal units of measurement.

METER
The measurement technology used by the METER level transmitter is the emission of a short
ultrasonic pulse. The ultrasonic wave propagates towards the surface of the product to be
measured, bouncing back on its surface towards the sensor. The time interval that elapses
between the emission and the reception of the wave is called the light time and is proportional
to the distance measured, therefore to the level.

RWL
The instrument emits high frequency pulses through a probe and causes them to pass through it.
The pulses are relected from the surface of the product, detected by the electronic microprocessor
unit and converted into “GODA” measuring technique level data, combined with the
management system, RWL units can also be used in particularly demanding process conditions
such as: high temperature, high pressure, low dielectric constant etc.

Microwave level
measurement (RADAR)
Levels
RPL devices are instruments for level measurement without contact with the product. The radar pulses emitted by
the antenna are relected from the surface of the product and subsequently received by the antenna itself. The builtin management system on board the RPL devices exploits the light time to derive the distance of the surface of the
product from the probe and, consequently, the level. Using the alphanumeric coniguration display, it is possible,
in addition to entering all the data for level measurement, to display and isolate any false level echo signals.
Software is available for coniguration and calibration with a PC via the COMWAY converter, also with the HART
communication protocol.

The absence of a separation
liquid between the membrane and
the
pressure sensor, “Dry-Pressure”
measurement technology, allows for
superior technological performance in
terms of overpressure, small temperature
drifts, high stability and accuracy.
P-AK
with HART Protocol
The process pressure is transmitted
through the insulation diaphragm to the
sensitive membrane housed at the centre
of the sensor. Similarly, the reference
pressure is transmitted to the opposite
side of the sensitive membrane.
The sensitive membrane is then bent in
proportion to the pressures applied. This
bending is converted electronically into
an analogue signal - 4 to 20 mA .
There are 3 different sensors:
- Ceramic sensors (C)
- Silicon sensors (A)
- Metal ceramic sensors (C1)

The different possible configurations, like

The process pressure is
transmitted through the
insulation diaphragm and
the filling oil to the sensitive
membrane housed at the
centre of the sensor.
Similarly, the reference pressure is
transmitted to the opposite side of the
sensitive membrane.
The sensitive membrane is then bent in
proportion to the pressures applied. The
bending of the sensitive diaphragm gives
rise to a difference in capacitance
between the two capacitors composed of
the same sensitive diaphragm and the two
fixed plates.
The difference in capacitance generated
by the sensor is electronically converted
into a 4-20 mA two-wire analogue signal
by means of a modulation.

Remote control
– Alarm configuration. When the status changes,
the device sends a text message alert, with a
notification when the condition returns to normal,
if applicable. One of the digital inputs can be
configured independently as an alarm in the event
of a mains power failure (optional buffer battery
required).
– The count configuration enables the acquisition of
pulses from totalisers or event-counters and stores
the totalised count at set time intervals
4Change the status of the 4 relays
available remotely
Following the receipt of a message (also via text
message) containing a precise command, the device
changes the relay activation status.

which shows the instantaneous situation of the
inputs (both analogue and digital), relays and any
alarm conditions.
4Set up to five different telephone
numbers
To send alerts via text message. Each signal
connected can be associated with a specific text to
facilitate reading the message. Alternatively, the
“VOC” version is available for sending prerecorded voice messages

SK 2040 GSM Alarm MASTER /
SLAVE Version
The SK 2040 GSM Alarm devices, in the MASTER / SLAVE versions,
manage the status of a relay on a remote device according to the status
of an input on said device.
It is possible, for example, to use a pair of SK 2040 GSM alarms for
autonomous management of a remote pumping station in relation to the
tank: when the water level goes down (signalled by a float), the device
on the tank calls the remote lifting device via a modem to activate
pumping.
Conversely, when the water level in the tank reaches the set level (the
status of the float changes), the device calls the lifting device again, to
stop pumping. In this way, it is possible to set the number of relays to
control on the remote device (it is therefore possible to control up to four
different pumps lifting from four different tanks), and it is obviously
possible to define the number of call attempts in the event of a
communication error (line busy, no GSM signal etc.) as well as the
interval between one call and the next.
Remote control
At the end of the attempts, if the activation of the command is not
successful, it is possible to send a text message to be sent notifying of the
failed activation.
88
4GPRS: this enables the control unit
to be used as part of a larger
centralised remote control network,
with data exchange via the TCP/IP
protocol
4Expansion of number of signals: via
the RS 485 serial port, the control
unit can be connected to other
boards to expand the number of
I/O signals that can be managed.

Recorders
S145 Line
Continuous trace recorder with text printing and dot matrix LED
The recorder makes it possible to record up to three channels, all
galvanically isolated by opto-isolators. The measurement values are read
on the scale or display. Channel one can also write a text, in addition to
the curve of the measured value.
The mechanical zero setting of all the channels takes place by means of
Hall effect sensors. The watch-dog controls the operation of the recorder
and in the event of a fault commands a new restart. The configuration
data is stored in an EEPROM. In the event of a power failure, the clock
is kept running by a battery.
Current and voltage signals, thermocouples, RTDs, resistance transmitters
and potentiometers can be connected to the input of all recorders. The
corresponding linearizations are performed automatically. There are
some optional features such as: eight logic inputs for command functions,
the logic-mathematic module which, in many cases, enables individual or
complex adaptation of the measurement. The ER8 external relay module,
for assembly on a DIN guide, enables the recorder to be equipped with
eight outputs per alarm. It is also possible to feed a two-wire transducer
by means of galvanically isolated voltage.
S145 Print
Dotted line recorder with text printing and dot matrix LED
The S145 Print is available with 3 or 6 measurement inputs,
galvanically isolated from each other. The assessment of the values
measured by the recorder may be assisted by the printing of texts.
Instrument programming is possible with either the 8 keys on the front or
with a PC and Setup program. The configuration data is stored in
EEPROM.
For the configuration or control of the parameters or to display the values
measured, the instrument has a dot matrix display with 24 characters.
Thermocouples, RTDs, resistive transducers, potentiometers, voltage or
current are possible as input signals. The corresponding linearization is
loaded automatically. It is also possible to enter a linearization to
customer specification using the Setup program.
Recording
In the basic S145 Print version, the following can be supplied as
standard: four Open-Collector outputs to report the exceedance of limit
values and for faults and eight event traces. There are eight logic inputs
for command functions.
