General Model EJA118W, EJA118N

Specifications and EJA118Y
Diaphragm Sealed Differential
GS 1C22H1-E Pressure Transmitters [Style: S2]

Diaphragm seals are used to prevent process medium form

entering directly into the pressure-sensing assembly of the
differential pressure transmitter, they are connected to the
transmitter using capillaries filled with fill fluid.
Model EJA118W, EJA118N and EJA118Y Diaphragm
Sealed Differential Pressure Transmitters can be used to
measure liquid, gas, or steam flow, as well as liquid level,
density, and pressure. They output a 4 to 20 mA DC signal
corresponding to the measured pressure differential.
The transmitters also feature remote setup and monitoring
through communications with the model BT200/100 BRAIN
TERMINAL, CENTUM CS/XL system etc.
