• Model-EJA440E-Gauge-Pressure-Transmitter
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 and PROFIBUS PA protocol types are also available.

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