Yokogawa EJA110A Differential Pressure Transmitter

Yokogawa EJA110A Differential Pressure Transmitter

 

The high performance differential pressure transmitter model EJA110A can be used to measure liquid, gas,
or steam flow as well as liquid level, density andpressure. 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™ terminaland CENTUM CS™ or XL™ or HART® 275 host.
