Yokogawa Differential Pressure Transmitter, EJA110E
The high performance differential pressure transmitter EJA110E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.

EJA110E outputs a 4-20 mA DC signal corresponding to the measured differential pressure. Its accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications.

Other key features include quick response, remote set-up using communications and self-diagnostics.

FOUNDATION Fieldbus, PROFIBUS PA and 1-5 Vdc 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.
