General Specifications Model EJA3W and EJA3N Diaphragm Sealed Gauge Pressure Transmitters GS 1C22J3-E [Style: S2] Diaphragm seal is used to prevent process medium from entering directly into the pressure-sensing assembly of the pressure transmitter. It is connected to the transmitter using capillary filled with fill fluid. Models EJA3W and EJA3N Diaphragm Sealed Gauge Pressure Transmitters can be used to measure liquid, gas or steam pressure. They output a to 2 ma DC signal corresponding to the measured pressure. The models EJA3W and EJA3N feature remote setup and monitoring through communications with the model BT2/1 BRAIN TERMINAL, CENTUM CS/XL system etc. STANDARD SPECIFICATIONS Refer to GS 1C22T2-E for Fieldbus communication type marked with.
