All dimensions in mm.
Intended
Use
The Capacitance Diaphragm Gauges of the CDG025 series are
intended for absolute pressure measurement of gases in their
respective pressure ranges (
→ 3).
The gauges belong to the SKY
®
Smart Sensors family and can
be operated in connection with an INFICON Vacuum Gauge
Controller (VGC series) or another appropriate measuring unit.
Function
The Capacitance Diaphragm Gauge consists of a capacitive
sensor element made of aluminum oxide ceramics and electro-
nics which convert the capacitance into a DC voltage output sig-
nal.
The output signal is linear to the measured pressure and inde-
pendent of the gas type.
