Intended Use

The Pirani Capacitance Diaphragm Gauge PCG55x has been

designed for vacuum measurement of gases in the pressure

range of 5×10-5 … 1500 mbar.

It must not be used for measuring flammable or combustible

gases which react in air.

The gauge is intended for operation in connection with an

INFICON Vacuum Gauge Controller VCG401, 402, 403 or with

another suitable controller.

Functional Principle

The PCG gauge is a combination gauge consisting of a Pirani

sensor and a diaphragm capacitive sensor. Both sensors are

constantly active.

At low pressures, only the signal of the Pirani sensor is used for

pressure measurement; at high pressures, only the signal of the

diaphragm capacitive sensor. To determine the output signal in

the intermediate range, both signals are used proportionally to

the pressure.
