General Model EJA110A

Specifications Differential Pressure Transmitter

GS 1C21B1-E

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 corre-
sponding to the measured differential pressure. Model
EJA110A also features remote setup and monitoring
through communications with the BRAIN™ terminal
and CENTUM CS™ or mXL™ or HART® 275 host.
