Differential Pressure Transmitter With Remote Diaphragm Seals - China

Description:

Universal remote control differential pressure transmitter provide several credible measure method for avoiding the medium contact the membrane of the transmitter, application as follow.

1 - transmitter need to be isolated from high temperature medium

2 - medium is able to corrupt the sense organ of the transmitter

3 - suspension or High Viscosity medium

4 - medium would curing or crystallization

5 - If change the medium, the connection need to be cleaned strictly.

6 - connection must keep clean.
