Intended Use
The temperature controlled SKY™ Capacitance Diaphragm
Gauges of the CDG045 and CDG045-H series are intended
for absolute pressure measurement of gases in the pressure
ranges specified in section "Validity".
The gauges can be operated in connection with an INFICON
Vacuum Gauge Controller or another appropriate controller.
Functional Principle
The SKY™ Capacitance Diaphragm Gauges consist of a
capacitive sensor element made of aluminum oxide ceramic
and electronics which convert the capacitance change into a
DC voltage output signal.
The output signal is linear to the measured pressure and
independent of the gas type.
The sensor is heated and its temperature kept constant at
45 °C to prevent contamination by process products and by
(0304)
products.
