Details

Yokogawa EJX440A High Static Gauge Pressure Transmitter

The high static gauge pressure transmitter EJX440A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam pressure.

 

The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat trace breakage.
The EJX series is available with BRAIN, HART, and FOUNDATION™ fieldbus communication protocols.
