ECA110A type differential pressure transmitterDetailed product description：

The ECA110A differential pressure transmitter is used to measure the liquid, gas, or vapor level, density, and pressure, and then convert it into a 4-20mADC current signal output. ECA110A can also communicate with the HART275 handheld controller for setting, monitoring, and other purposes.
