Fig. 2: Process pressure measurement VEGABAR 82
Depending on the version, the VEGABAR 82 is also suitable for
electronic differential pressure measurement. For this, the instrument
is combined with a Secondary sensor.

sensor combination
You can find detailed information in the operating instructions of the
respective Secondary sensor.
The sensor element is the CERTEC
®
measuring cell with robust
ceramic diaphragm. The process pressure deflects the ceramic
diaphragm and causes a capacitance change in the measuring cell.
This capacitance change is converted into an electrical signal and
outputted as measured value via the output signal.
