Applications in mobile and stationary hydraulics are among the most demanding in terms of robust and reliable sensor requirements. Trafag pressure transmitters are used in applications from high accuracy test benching to heavy construction and agricultural equipment. They are proven for long term stability in extremely harsh environments from the dusty heat of deserts to the icy cold of sub-arctic forests. The reliable pressure transmitters with great long-term stability are highly prized for stationary hydraulics as well, for they avoid costly production interruptions.

Post category:2021 Trafag

Trafag has succeeded in unifying the highly dynamic response behavior of a test bench sensor and the extreme robustness of a mobile hydraulic pressure transmitter by combining thin-film-on-steel measuring cells and an ASIC developed in-house. The Trafag ASIC TX with an innovative parallel mixed-signal structure is the key to a response behaviour at nearly unlimited speed. In many applications, above all in the testing field, the aim is to record highly dynamic pressure curves, e.g in order to analyse the opening and closing performance of valves, track pressure curves of explosions and explosive pressure expansions or to examine brief pressure peaks in hydraulic systems. Transmitters for industrial applications on the market are generally…
