Differential Pressure Transmitter

differential pressure transmitter
Model :EJA110A

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™ terminal and CENTUM CS™ or XL™ or HART® 275 host.

Specification :

Zero Adjustment Limits

Zero can be fully elevated or suppressed, within the Lower and Upper Range Limits of the capsule.
External Zero Adjustment “”
External zero is continuously adjustable with 0.01 % incremental resolution of span. Span may be adjusted locally using the digital indicator with range switch.
Mounting Position Effect
Rotation in diaphragm plane has no effect. Tilting up to 90 ˚ will cause zero shift up to 0.4 kPa {1.6 inH2O} which can be corrected by the zero adjustment.

Output “”

Two wire 4 to 20 mA DC output with digital communications, linear or square root programmable. BRAIN or HART FSK protocol are superimposed on the 4 to 20 mA signal.

Failure Alarm

Output status at CPU failure and hardware error;

Up-scale: 110%, 21.6 mA DC or more(standard)

Down-scale: -5%, 3.2 mA DC or less -2.5%, 3.6 mA DC or less (Optional
