Pressure Transmitters

Technology

A pressure transmitter measures pressure, typically of gases or liquids. A pressure transmitter senses a pressure and outputs a proportional current signal. These pressure transmitters generally consists of two main parts, a primary sensing element, which is in direct or indirect contact with the process system, and the secondary electronic bundle which converts and constrains the output of the sensing element into a standard transmission signal. A pressure transmitter can be used to measure various form of pressure. It can be used to measure gauge pressure, absolute pressure, or vacuum pressure.
