Gauge Pressure
Gauge pressure transmitters are used to measure the pressures of liquid, gas and steam. These transmitters produce a measurement by comparing a pressure relative to atmospheric pressure.
Modern technology pressure sensors are able to accurately, quickly, and reliably make pressure measurements in environments from high pressure LNG to low-static-pressure environments like Food and Beverage, where the measurements need to be smaller and more precise. With features such as digital sensor technology and multi-sensing transmitters, we have solutions you need for simple or complex pressure measurement applications.
Gauge pressure transmitters are used to measure the pressures of liquid, gas and steam. These transmitters produce a measurement by comparing a pressure relative to atmospheric pressure.
Absolute pressure transmitters are ideal for use in applications where the measurement will not be affected by atmospheric pressure. These transmitters compare a pressure relative to absolute (zero) pressure. The measurement output is always positive.
Differential Pressure (DP) transmitters measure the difference between two pressures. They use a reference point called the low-side pressure and compare it to the high-side pressure. Ports in the instrument are marked high-side and low-side.
A multi-variable transmitter combines a differential pressure transmitter, a gauge pressure transmitter, a temperature transmitter and a flow computer into one unit. The flow computer is programmed with application information and uses the three measured inputs to calculate the mass flow.
