PRESSURE TRANSMITTERS
Trafag is a technology pioneer in the miniaturization of rugged pressure transmitters.
Trafag pressure transmitters are used for the electronic measurement and evaluation of pressure values. They are available in many different versions with regard to pressure and electrical connections, measurement procedures, electric output signals, and approvals (CE, Ex, Shipbuilding, Railways).
At the very heart of Trafag pressure transmitters are pressure sensors based on either thin-film-on-steel or thick-film-on-ceramic technology derived from own in-house development and production. This ensures that the pressure sensors and associated electronics are perfectly attuned to one another, a feature subsequently successfully confirmed through reliable function and long serviceable life.
Trafag also develops and manufactures products specifically to customer requirements. Please contact us for further details.
