Description of Diaphragm Seals
Diaphragm seals are traditionally used when a standard pressure transmitter should not be exposed to the process pressure directly. Diaphragm seals typically protect the pressure transmitter from one or more damaging aspects of the process media. Consideration for using a diaphragm seal should be made in the following circumstances.
High Process Temperature
Process Media is Viscous or Contains Suspended Solids,Subject to Solidifying ,Corrosive
Process Application Requires Sanitary Connections,Subjects the Measuring Instrument to Hydrogen Permeation
Tank Level Applications with Maintenance Intensive Wet Legs
Tank Application with Density or Interface Measurements
Measuring Instrument Requires Remote Mounting
