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 BT200/100 BRAIN TERMINAL, CENTUM CS/XL system, etc.
