Universal remote control Differential Pressure Transmitter
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
dium is able to corrupt the sense organ of the transmitter
3.suspension or High Viscosity medium
dium would curing or crystallization
5.If change the medium, the connection need to be cleaned strictly.
nnection must keep clean.
