Favorite

The high performance gauge pressure transmitter absolute pressure transmitter EJX610A feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. 

EJX610A output a 4 to 20 mA DC signal corresponding to the measured pressure. They also feature quick response, remote setup and monitoring via BRAIN or HART communications, diagnostics, and optional status output for pressure high/low alarm.

The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage. 

FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified by TÜV as complying with SIL 2 for safety requirement.
