The isolating diaphragm CSS consists of the components: separating
diaphragm, process fitting as well as transmission line (capillaries).
The components are fully welded with each other and with the
associated differential pressure transmitter and represent a hermeti-
cally sealed system.

2.2 Principle of operation

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