Description
BP380CG/CD pressure and 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.connection must keep clean
