E JA120A differential pressure transmitter for measuring liquid, gas or steam level, density and pressure, and then converted to a current signal output of 4 ~ 20m ADCTM. EJA120A differential pressure transmitter also can be used with handheld BRAIN, TMYHC4150, CENTUMCS, FieldMate, HART 375 communicate with each other through their set, monitor and so on. EJA intelligent transmitter features: sensors using silicon resonant sensor frequency signal is directly output, high-precision direct docking with the microcontroller, the general accuracy of 0.065 high stability and high reliability, over 100,000 times in a row. Pressure tests five years of continuous work does not require the full support of zero adjustment BRAIN / HART / FF / PROFIBUS from four fieldbus communication protocol External zero / span calibration
