Request Information
Favorite

The high performance gauge pressure transmitter EJA440E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure.

The EJA440E outputs a 4 to 20 mA DC signal corresponding to the measured pressure.

It also features quick response, remote setup and monitoring via BRAIN or HART communications and self-diagnostics. FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available.

All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.
