HVS4000 at a Glance
•
The HVS4000 is a +24VDC
powered toxic gas detector
comprised of a base unit,
interface module (IM) and
electrochemical cell
•
Galvanically isolated
intrinsically safe design of the
(IM) module supports sensor
field replacement without the
need for special tools or hot
work permits
•
Complements our HVS400
Series products and provides
a “Total Toxic Solution” for
application in Chlorine rooms.

Interface Module
•
The HVS4000 Interface Module (IM) is encapsulated in an anodized
aluminum housing enabling sensor information to be processed at the
point of detection. The HVS4000 provides a 4-20mA output signal
proportional to the gas concentration at the Base Unit
• IM Features:
– Galvanically isolated Intrinsic Safety Barrier to the internal electronics
of the IM
– Electrical conditioning circuitry for the electrochemical cell
– Mechanical and electrical interface for the electrochemical cell
– Explosion proof conduit seal from the Base Unit to the IM
– Explosion proof housing for the Intrinsic Safety Barrier
– One I/O pair for digital serial communication to and from the Base
Unit and IM
– One +24VDC / COM GND pair for power into the Interface Module
Base Unit

Gas Enters Through
Permeable Membrane
Target gas diffuses through the
diffusion barrier limiting the amount of
gas entering the sensor. It then diffuses
through the gas permeable membrane
until it reaches the sensing electrode
that produces ions.
The REFERENCE electrode provides
voltage stability for the sensing
electrode, and the electrodes (sensing
and reference) are constructed of
materials specific to the target gas. This
specificity creates the ion flow current
central to the sensor’s detection
method.
The HVS4000 integral electronics
provides temperature compensation,
and the amount of ions produced by the
target gas molecules striking the
sensing electrode, is proportional to gas
concentrations. The HVS4000’s
microprocessor then produces a linear
4-20mA output signal.

Simple Calibration
•
Apply and hold the magnet over the HVS logo on the cover of the Base Unit. Wait until AC appears in
the display window. Remove the magnet to select AC. The unit is now in Calibration Mode.
•
The display flashes the Remaining Sensor Life. The user can choose to reset or not to reset the
sensor life at this point.
•
The Remaining Sensor Life flashes while the unit is being set to zero. Once the unit has been set to
zero gAS appears in the display window
•
Apply the calibration gas concentration to the sensor (50% FS of the required range of detected gas).
The display changes from gAS (apply gas) to CP (Calibration in Progress) indicating that the sensor is
responding to the calibration gas. While the unit is reading the gas concentration, the menu is
disabled
•
After three to five minutes, the display changes from CP to CC indicating that the calibration is
complete
•
Remove the gas and wait for the unit to return to normal operation. The display may indicate a few
percent FS and will eventually drop to 0. If a unit time out occurs the user receives a calibration fault
The HVS4000 is now calibrated and the new sensor SPAN values (or calibration constants)
are stored in the non-volatile memory (EEPROM)
Changing a Sensor
•
Each spare sensor is shipped in a plastic bottle. DO NOT remove the sensor
until you are ready to apply power to the system. To ensure proper sensor
response, each HVS4000 must be calibrated in the field upon initial installation
•
If the new sensor is in a plastic storage container, then remove the lid ring and
uncap the jar. Remove the sensor from the container
Save the storage container for later use.
Changing a Sensor
• Note: Certain types of sensors are shipped with a shorting wire across two
(2) pins. This wire must be removed prior to installing in the HVS4000.
Ammonia (NH3) sensors are shipped attached to a small circuit board with a
battery. Remove the battery board prior to installing in the HVS4000.
•
Save both the shorting wire and/or battery board for later use.

Methane (CH4) gas generated
from anaerobic digesters also
contains hydrogen sulfide (H2S)
resulting from decomposing
sludge. The H2S gas is usually
removed. Methane gas is used
to fuel compressors, boilers
and engines. Any unused gas is
then flared off to the
atmosphere. Applications exist
for Models S4000C/T and
IR2100 Infrared Point Gas
Detector because of high O2.
The Model IR5000 is also used
for CH4 detection in large waste
treatment plants.
Sludge Dewatering
Outgoing Sludge
to Incinerator
De-watering System
Model S4000T Intelligent Sensors
are positioned both sides
of the compressor
Incoming
Sludge
Incoming sludge from waste
treatment facilities contains
hydrogen sulfide and methane
gas. The sludge is transported
through a spiral conveyor into
the de-watering system where
the water is removed. The
outgoing conveyor transports
the remaining solids to an
incinerator. Model S4000T
Intelligent Sensors are
positioned so that during
operation of the compressor
any escaping H2S will be
detected.
Wet/Dry Wells & Lift Stations
S4000C/T and HVS4000
Manhole
Sewer or Vault
Wet wells and dry wells are confined
spaces which can develop a buildup of H2S and CH4. This gas
concentration can become explosive
and/or toxic to the level of personnel
danger. Because personnel are
required to service these areas, O2
deficiency monitors are installed to
ensure that oxygen levels do not
drop below the regulated levels
needed to sustain life.
Models HVS4000 / HVS400 and
S4000C/T’s can all be used for these
applications.

Landfills produce Methane

from decomposing

methane is used to fuel
compressors, engines and
co-generation plants.
These facilities provide an
excellent opportunity for
Model S4000C Intelligent
Sensors to detect the
methane gas.
Cogeneration
S4000C Gas Detector
Many sewage treatment facilities
use Methane generated from
digesters to power electrical
generating plants. This power is
used to run the facilities as a
supplement to purchased power
from utility companies. Model
S4000C Intelligent Sensors are
used to monitor leaks in the cogeneration building
Selling against the

Advantages of HVS4000 and HVS400 are:
– HVS400 is small and compact by design with a 4-20mA signal that can be used as
the “front-end” sensor for a SCADA system directly
– HVS400 2-wire self contained transmitter with sealed electronics is very suitable for
corrosive chlorine service
– Calibration prompts can be viewed on the LED window, without the added expense
of a transmitter housing with a display
Selling against the
Competition
– End-users have reported that the HVS400/4000 is rugged and looks more like an
industrial product than competitors… such as “Foxcroft, Capital or Regal”… who more
closely resemble “Swimming Pool Type” chlorine detectors
– Most Cl2, SO2, H2S applications do not require a XP rated enclosure, however that’s all
many competitors have to offer. The general-purpose enclosure on HVS400 sensors,
will keep system cost down
– End-users like the “potted & sealed” HVS400 electronics because corrosive gases
cannot access the PC board components
– Galvanic isolation on the HVS4000 allows hot swapping of sensors and remaining
sensor life, reduces downtime by providing a “heads-up” on sensor life
– Dual redundant MODBUS RS485 interface provides remote operation of all functions
