Instrumentation / Primary instrumentation (flow, temperature, level and pressure)

The EPN-S electronic pressure switch is based on the proven EPN family of transmitters. As a guarantee of precision and reliability, it covers a wide temperature range and offers excellent long-term stability even in the most demanding environments such as shipbuilding and railway applications. The switchpoint is factory-set or can be programmed on site using the Trafag Sensor Communicator.
