Descriptions Of Trafag ECR 8478 Railway Pressure Transmitter
The Trafag ECR 8478 is a pressure transmitter with high safety and dependability characteristics that was created especially for railway applications.
This sensor uses cutting-edge technology to detect pressure accurately in a range of harsh environments. It satisfies the needs of the railroad sector, including resilience to environmental fluctuations, power surges, and vibration. For monitoring the pressure of air controls, braking systems, and other parts, the Trafag ECR 8478 is the perfect tool.
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.
