Gauge Pressure Transmitter introduction

Gauge pressure transmitters are used in reference to the atmospheric pressure. If the gauge pressure is found to be higher than the outside pressure, then it is referred to as positive pressure. However, if the gauge pressure is lower than the atmospheric pressure, then it is known as negative pressure.


Gauge pressure transmitters feature a single pressure port. The transmitter may feature a measuring cell, seal diaphragm, and filling liquid. Ambient pressure is the main input variable, which is transferred to the pressure sensor through the seal diaphragm as well as the filling liquid. A gauge pressure transmitter allows ambient air pressure to be exposed to the negative side of the diaphragm. This enables an accurate measurement in reference to the ambient pressure.


Gauge Pressure Transmitter Feature


With the piezoresistive pressure sensor technology, it gives outstanding linearity, repeatability and hysteresis. While with the robust circuit design, it features a good resistance of EMI, and protection for instantaneous high pressure and surge interfere of thunder, noise and sharp pulse, etc which make it work reliably and stably in the rough environment.

Gauge Pressure Transmitter specification


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 transmitters can be affected by fluctuations in the local ambient pressure. Measurements above the ambient air pressure are represented as a positive number, while 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).
