Diaphragm Sealed Differential Pressure Transmitter - JC-E118W/N/Y

Overview

Sealed diaphragms are used for prevention of medium in the pipelines directly entering pressure

sensors assembly in the differential pressure transmitters, which are connected with transmitters

with the help of capillary tubes filling fluid inside.

JC-E118W, JC-E118N and JC-E118Y diaphragm sealed differential pressure transmitters are used for measuring flow rate, density

and pressure of gas, liquid and steam , and then outputs 4~20mA DC power signal corresponding

to measured differential pressure.

Because they can communicate with Hart system, remote set and monitor can be set.
