Gauge Pressure

What Is a Gauge Pressure Transmitter?

A gauge pressure (GP) transmitter compares a process pressure against local ambient air pressure. Gauge pressure transmitters have ports to sample the ambient air pressure in real-time.

Today’s highly accurate gauge pressure sensors can be affected by fluctuations in the local ambient pressure. Measurements above the ambient air pressure are represented as a positive number, while a negative number represents measurements below ambient. A gauge pressure measurement is indicated by the letter ‘g’ following the unit of measure of the reading (i.e., inH₂O(g) or psig).
