EJA118W Diaphragm SeaLED Differential Pressure Transmitters

Features :

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.
