EJAX120A Micro differential pressure transmitterDetailed product description：

The EJAX120A micro differential pressure transmitter is used to measure the liquid, gas, and vapor levels, densities, and pressures, and then convert them into 4-20mADC current signals for output.
EJAX120A can also communicate with HART275 handheld controllers for setting, monitoring, and other purposes.
2、 Functional specifications
