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). Two different sensor technologies are available, namely thin-film-on-steel (weld-sealed design without O-rings) and thick-film-on-ceramic. Trafag also develops and manufactures products specifically to customer requirements.

PRESSURE TRANSMITTERS

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 is a technology pioneer in the miniaturization of rugged pressure transmitters.

Product programme

The following information provides an initial programme overview. The individual product features are not freely combinable with one another. Further information can be obtained by consulting Trafag`s product catalogs and data sheets.

Sensor technologies

Thin-film-on-steel technology:

Measurement is effected according to the strain gauge principle. Through the force effect of the sample medium, the strain gauge bridge is deformed, changing its electrical characteristics.
Features:

Very good long-term stability
Ability to endure elevated medium temperatures
Completely weld-sealed sensor system made of stainless steel without O-rings
Very high resistance to overpressure; ideal for rated values up to 2000 bar

Thick-film-on-ceramic technology:

Measurement is effected according to the strain gauge principle. Through the force effect of the sample medium, the strain gauge bridge is deformed, changing its electrical characteristics.

Features:

Resistant to aggressive media
Ideal for low-pressure ranges
Sealed with an O-ring
