2.2 Principle of operation
Chemical seals are used if a separation between medium and pres-
sure transmitter is necessary, particularly with:
•
High product temperatures
•
Corrosive products
•
Strong vibrations at the measurement point
Further application areas for the VEGADIF 65 with chemical seal CSB
are:
•
Density measurements
•
Interface measurements
The process pressure acts on the separating diaphragm. This dia-
phragm transmits the process pressure through the capillary line to
the sensor element of the differential pressure transmitter.
