ECA210A and ECA220A flange mounted differential pressure transmitters are used to measure liquid, gas, and vapor pressures and convert them into 4-20mADC current signals for output. ECA210A and ECA220 can also communicate with each other through the HART275 handheld controller for settings, monitoring, etc.
