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 NAE 8256 Marine Pressure Transmitter
The engine and shipbuilding pressure transmitter NAE 8256 features an extremely robust and stable thin-film-on-steel sensor element. The NAE 8256 is the smallest pressure transmitter of its kind with ship approvals. The wide temperature range from -40°C up to +125°C and triple overpressure safety makes it the first choice in rough environments such as marine applications.
Main Features of NAE 8256 Marine Pressure Transmitter
- Measuring accuracy 0.3 %
- Completely welded steel sensor system without additional seals
- High resistance to over-pressure
- Excellent long-term stability
- Optional: Switching output 1 or 2 PNP
