EJA510A In-Line Absolute Pressure Transmitter
Brand: Yokogawa Electric CorporationThe absolute and gauge pressure transmitter model EJA510A and EJA530A can be used to measure liquid, gas, or steam pressure.
Both output a 4-20 mA DC signal corresponding to the measured pressure, and also feature remote setup and monitoring through communications with the BRAIN terminal and CENTUM CS or µXL or HART 275 host.
