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. 

Feature :

A reliable measurement method is provided to avoid the contact of the diaphragm of the transmitter with the

 pressure transmitter and differential pressure transmitter.Simulation type, zero point and range migration are

 adjusted by potentiometer, optional M2 and M3 field head, flange size and capillary length can be selected.
