Original Yokogawa EJX120A Differential Pressure transmitter


YOKOGAWA Differential Pressure Transmitter EJX120A

 

 

FEATURES: 

1.EJX120A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid.

2.The high performance draft range differential pressure transmitter EJX120A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure.

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

4.The EJX series is available with BRAIN, HART, and FOUNDATION™ fieldbus communication protocols.
