They are available in many different designs to suit pressure and electrical connections, measuring procedures, electrical output signals, and certifications (CE, EX, rail, and ship).
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.
Descriptions of Trafag EPI 8287 Industrial Pressure Transmitter
The industrial pressure transmitter EPI 8287 features an extremely robust and stable thin-film-on-steel sensor element from its well-proven predecessor EPI 8297. In combination with the new in-house developed ASIC TX, it offers a wide temperature range up to 125°C and triple overpressure safety which makes it the perfect solution for a wide range of demanding applications.
