ECA210A, ECA220A flange mounted differential pressure transmitter
Overview: ECA210A and ECA220A flange mounted differential pressure transmitters are used to measure liquid, gas, and vapor pressures and convert them
Product details
summary
ECA210AThe ECA220A flange mounted differential pressure transmitter is used to measure the pressure of liquids, gases, and vapors, and convert it into a 4-20mADC current signal output. ECA210A and ECA220 can also communicate with each other through the HART275 handheld controller for settings, monitoring, etc.
Functional specifications
output
