MEDIA COMPATIBILITY
The bulk micro-machined transducer features a stainless steel diaphragm with welded construction that
contains no O-rings, which makes them compatible with any gas or liquid that’s compatible with 304L
stainless steel. Some compatible gasses and liquids include refrigerants, glycol, motor oil, diesel, hydraulic
fluid, brake fluid, water, waste water, hydrogen, nitrogen and air.
INSTALLATION
LOCATION
Install the sensor in a location where it will not be exposed to extreme temperatures, vibration or shock.
Install the pressure sensor above or on the side of pipes, in a location where liquid will not drip on the unit.
Condensation can potentially build up and run down the harness, position the unit and harness so water
does not pool on the back of the sensor. Do not install the sensor at the end of a long run of pipe.
CONNECTION
The GP uses a standard ¼”-18 NPT external
fitting. Standard pipe fittings and installation
procedures should be used during installation.
Install pipe tape, thread sealant or other
suitable pipe compound when connecting the
sensor to the pressure source or any of the
accessories. For pressure ranges more than 500
PSI (3447.4 kPa), we recommend the use of a
sealant such as Loctite Hydraulic Sealant. Do
not use excessive amounts of sealant or you
might block the pressure going into the
transducer. Install the device using a wrench on
the hex flats provided. Do not use a strap
wrench on the body. When installing the GP
sensor, the torque limit is 150 in lbs (16.95 Nm),
Do Not over tighten. Overtightening metal
fittings may cause a slight zero shift. The use of
plastic fittings typically results in no noticeable
zero shift. The torquing effect does not
appreciably affect linearity or sensitivity. In
liquid pressure monitoring applications, air
present in the lines will cause erratic readings,
use bleed fittings to bleed off any air that has
been trapped before transducer installation.
WIRING INSTRUCTIONS
The transducer requires a supply voltage of +13
to 30 VDC with a minimum supply current of 25
mA (per unit) to power the loop. The transducer
is equipped with a Packard connector for easy
installation, and is designed for use with the GP
Harness. Install the GP Sensor onto the harness
then make the proper connections to the
harness. Connect the Power lead (Red) to the plus terminal of the supply voltage. Connect the Return lead
(White) to the Analog Input(+) terminal of the current measuring device(controller). Connect the
Common(-) terminal of the current measuring device to the Common(-) terminal of the supply voltage. If
the unit is equipped with a Shield Wire, it should be connected to the system or earth ground. See

Black wire is not used.
