Intended Use
The temperature controlled Capacitance Diaphragm Gauges of
the CCR 37X series are intended for absolute pressure
measurement of gases in their respective pressure ranges
(→3).
Functional Principle
A ceramic diaphragm is deflected by pressure. The deflection is
measured capacitively and converted into an analog linear out-
put signal by the digital electronics.
The output signal is independent of the gas type.
Very accurate pressure measurement is achieved by heating the
sensor to a constant temperature of 45°C which results in a com-
pensation of changes in the ambient conditions and a reduced
deposition of process products and by-products in process appli-
cations.

The gauge may only be connected to power sup-
plies, instruments or control devices that conform
to the requirements of a grounded protective extra-
low voltage (SELV) and limited power source
(LPS), Class 2. The connection to the gauge has to
be fused.
