If not indicated otherwise in the legends, the illustrations in this
document correspond to Capacitance Diaphragm Gauges with
the DN 16 ISO-KF vacuum connection. They apply to gauges
with other vacuum connections by analogy.
We reserve the right to make technical changes without prior
notice.
All dimensions in mm.
Intended Use
The temperature controlled Capacitance Diaphragm Gauges are
intended for absolute pressure measurement of gases in their
respective pressure ranges (
→  3).
The gauges can be operated in connection with a Nor-Cal
Vacuum Gauge Controller or another appropriate controller.
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 160°C which results in a
compensation of changes in the ambient conditions and a
reduced deposition of process products and by-products in
process applications. An integrated baffle protects the sensor
against coating.
