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 NAH 8254 Electronic Pressure Switch
The pressure switch NAH 8254 with 1 or 2 switching outputs and increased accuracy of 0.3% has an exceptionally long-term stable thin-film-on-steel sensor cell with triple (optionally 5-fold) overpressure protection. The robust design and the wide temperature range from -40°C to +125°C make the NAH 8254 the ideal solution when exact and reliable switching signals under rough environmental conditions are required.
