Basic Information :

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 EJA438W and EJA438N Diaphragm Sealed Gauge

Pressure Transmitters can be used to measure liquid, gas or

steam pressure. They output a 4 to 20 mA DC signal

corresponding to the measured pressure.

The models EJA438W and EJA438N feature remote setup

and monitoring through communications with the model
