User Manual
DESCRIPTION:
FEATURES:
The Model 375 submersible level transmitter is
specially designed to provide the convenience of
direct submergence in many types of liquids for
quick, accurate and reliable level measurement.
The 375 provides an economical, lighter weight
style for submersible level applications. The simple
design and rugged construction of this solid state
instrument provide long lasting service with virtually
no maintenance.
• Potted electronics for robust moisture intrusion
protection
• Low cost
• Solid state sensor for accuracy and reliability
• Lightweight and compact size
•Rugged 316 stainless steel housing with
excellent environmental protection to IP68
• Advanced digital compensation
The Model 375 indicates the level of liquid by
continuously measuring hydrostatic pressure via
its isolated sensing element, an ion implanted
silicon semiconductor sensor. The standard output
signal is 4-20 mA. For other input / output options,
consult factory. This design provides for excellent
linearity and repeatability, low hysteresis and long
term stability at an economical price.
• Easy to install and use
•Vented to the atmosphere through the surface
end of the cable (desiccant package supplied)
with PSIG reference units
• Reverse polarity and surge protected
• 2 wire, 4 to 20 mA output standard; other low
power voltage outputs available - consult
factory
The Model 375 is easy to install; simply lower
the sensor into a vessel or well. It’s that easy.
All the electronics are potted and mounted in a
submersible 316 stainless steel housing. A special
cable support bracket is also available. This gives
extra stability to the transducer when used with
longer lengths of cable (up to 2500 feet) or when
used in an agitated liquid. A conduit adapter is also
available.
• Standard submersible model with nose cone;
1/4-18 NPT male with nose cone removed for
pipe mount
• Flush 1" NPT process connection option for
pipe or vessel mounting.
APPLICATIONS:
A specially designed cable is factory installed
and sealed to insure liquid tight performance. The
customer connection end of the cable is sealed
and a desiccant package is installed to limit the
amount of moisture allowed to enter the barometric
reference of the sensor.
•Tanks
•Landfills
•Ponds
•Flood channels
•Rivers
•Pump control
•Lakes
•Lift stations
• Water wells • Low power/solar applications
The transducer is available calibrated for any span
needed, from 6 psi (13.8 ft of water) to 300 psi (692
ft of water).

Model 375 Transmitter Installation
WARNING: Remove power before
installing or servicing.
CAUTION: The cable grommet and
support are specially installed by
factory-trained personnel to insure
water-tightness. Any adjustment or removal of
these items may destroy the watertight feature
thus exposing the transmitter to water seepage,
an electrical short and transmitter failure. Any
adjustment or removal of the cable grommet or
cable support voids the warranty.
!
To install the Model 375 Transmitter, connect the
surface end of the cable to the Ametek Model
DDMC Meter Controller or other power source
and indicator. Suspend the transmitter into
a well or tank supported only by its attached
shielded electronic cable. Insure that the
opening in the well or tank cover is large enough
for possible future removal of the transmitter.
CAUTION: Waterproof cable should
not be kinked or nicked. Do not cut
off excess cable. This will remove the
sealed cable end, void the warranty and allow
water into the electronics housing. Permanent
damage will result. (Never cut or splice the
waterproof cable). The surface end of the cable
is used as the system's atmospheric reference.
This end is factory sealed and venting occurs
through a small tube. The tube should be connected to the desiccant kit provided with the
transmitter. It is recommended that this be installed in a dry, temperature stable environment.
!
Additional support to the transmitter is available
with an optional factory installed cable support.
The optional cable support is recommended
when using longer lengths of cable or when
suspending the transmitter into agitated liquids.
The cable support provides strain relief for the
excess stress found under these circumstances.
See diagram of Model 375 Transmitter with
cable support using optional factory or
customer supplied and installed support cable.

Surge or lightning protectors are available as
optional items and are strongly recommended
for protection from secondary surges or
lightning strikes. The units are easy to install,
are maintenance-free and respond in less than
one nanosecond. Install in accordance with the
instructions:
5. Keep the ground wire less than 1 foot long
and tie to a suitable ground rod or metal frame
ground. Surge capability is only as good as
the grounding method. All ground connections
must be installed.
6. Install all protectors in weathertight enclosures.
7. Run signal lines shielded and away from power
lines.
1. L
ightning protection devices should be placed
as close to the instrument as possible and
wired in accordance with National Electric
Code in an approved watertight enclosure.
8. Wire according to the Electrical Code.
9. When used for an intrinsically safe installation,
only one LMA912 should be installed in the
hazardous location. Do not substitute protector
types.
2. If the distance between the meter and
transmitter, or the meter and recorder is less
than 100 feet, only 1 protector per line may be
used.
CAUTION: This or any installation
cannot protect against a direct lightning
strike, or secondary strikes of sufficient
magnitude. Ametek cannot accept liability for
damage due to lightning or secondary surges.
!
3. U
se No. 10 AWG ground wire or better from
protector to earth ground.
4. P
rovide a separate ground for each run of
shielded cable or metal conduit.
