Intended use
The Barocel 7025 gauge is intended for absolute pressure measurement of gases in their
respective pressure ranges, see Installation on page 13. The unit is clean room compliant and
double protected against contamination.
The gauges belong to the Barocel 7000 series and can be operated in connection with an
Edwards TIC controller or another applicable unit.
Function
The Barocel 7025 gauge has a capacitive sensor element made of aluminium oxide ceramics
and electronics which convert the capacitance into a direct current (d.c.) voltage output
signal.
The output signal is linear to the measured pressure and independent of the gas type.
