Introduction
Product identification
Specify the information given on the gauge nameplate in all communications with Edwards.
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.
Before using this gauge
Make sure that the model is the same as you ordered and no damage occurred during
shipment.
Read this instruction manual before you install, operate, inspect, or service this gauge to
familiarize yourself with safety precautions, specifications and operations.
