I. EJA120E-DES4J-917DA High-Performance Differential Pressure Transmitter Overview The EJA120E High-Performance Differential Pressure Transmitter utilizes single-crystal silicon resonant sensor technology,
suitable for measuring the flow, level, density, and pressure of liquids, gases, or steam.
The EJA120E converts the measured differential pressure into a 4~20 mA DC current signal output, featuring fast response, remote setting, and self-diagnosis functions.
