Yokogawa EJA110-EMS4B-92DB DIFFERENTIAL PRESSURE TRANSMITTER
EJA110A general introduction:
The high performance differential pressure transmitter model EJA110A can be used to measure liquid, gas, or steam flow as well as liquid level, density and pressure. It outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Model EJA110A also features remote setup and monitoring through communications with the BRAIN™ terminal and CENTUM CS™ or XL™ or HART® 275 host.
