The GP is a two-wire, 4-20 mA gage pressure transducer.

These units have been designed to provide excellent accuracy and reliability in commercial, industrial, and process control applications. The GP pressure transducers are compatible with a wide range of gases and liquids. They are available in ranges from 0 to 15 PSIG up to 0 to 3000 PSIG.

All units are accurate to +/- 0.5% or +/- 1% of full scale based on the range ordered. The GP pressure transmitter offers a combined repeatability, hysteresis, and non-linear factor that is typically below +/- 0.15% of full scale. The GP pressure transducers are both EMC compliant and reverse polarity protected.

The pressure port is a 1/4”-18 NPT Male fitting made of 304L stainless steel. A 2’ shielded cable is supplied for making all of the proper connections.
