2.2 Principle of operation
Chemical seals should be used if a separation between medium and
pressure transmitter is necessary, particularly with:
l
High product temperatures
l Corrosive products
l
Strong vibrations at the measurement point
The process pressure acts on the separating diaphragm. This
diaphragm transmits the process pressure through the capillary line to
the sensor element of the differential pressure transmitter.
