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 EXNA 8854 Ex Pressure Transmitter
ATEX and IECEx have validated the intrinsically safe EX pressure transmitter EXNA 8854 for use in mining, Ex-Zones 0, 1, 2 (gas), 20, 21, and 22 (dust). It can be suitably customized for nearly any application because of its many variations and pressure ranges, which vary from 0.1 to 1000 bar.
