3.2 Principle of operation
VEGABAR 29 is suitable for applications in virtually all industries. It is
used for the measurement of the following pressure types.
•
Gauge pressure
•
Absolute pressure
•
Vacuum
Measured products are gases, vapours and liquids.
The device is especially suitable for applications with higher tempera-
tures and high pressures.
The VEGABAR 29 is suitable for the measurement of the following
process variables:
•
Process pressure
•
Level
Fig. 3: Process pressure measurement VEGABAR 29
The process pressure acts on the sensor element via the process dia-
phragm. The process pressure causes a resistance change which is
converted into a corresponding output signal and output as measured
value.
Piezoresistive sensor element
Measuring ranges up to 100 bar: piezoresistive sensor element with
internal transmission liquid is used.
