About Pressure Transmitters
Pressure transmitters are electronic pressure gauges and are used to measure and monitor pressure. The term pressure transmitter is also often used for pressure transducers or pressure sensors. However, this is not a synonym, since the term pressure sensor in the narrower sense only describes a part of the pressure transmitter.
Description of Trafag EXNT 8292 Ex Pressure Transmitter
