No need for calibrated pressure source

03 May 2016

As part of its GP:50 range of pressure sensors and transmitters for hazardous and harsh environments, Interface Force has launched the Model 1171 field rangeable pressure sensor. A rugged, compact transmitter, the 1171 has been designed for use in severe weather conditions such as those encountered offshore in the energy and maritime sectors.

Pressure ranges from 50 through 100,000 PSIS, PSIA and PSIV and is 4-20mA loop powered. The external zero, span and calibration controls are hermetically sealed and easily adjusted with the help of a magnetically coupled drive system.

The unit allows for 5:1 ranging of the transmitter’s standard pressure range, so there is no need for a calibrated pressure source.

Completely sealed, the GP:50 Model 1171 is an all welded constructed unit and using 15-5 and 316 stainless steel in the pressure activity means that it is completely watertight and corrosion resistant. For added reliability, the unit is designed without an ‘O’ ring that can be susceptible to wear.
