Fig. 3: Process pressure measurement VEGABAR 28

The sensor element is the Mini-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.

Fig. 4: Configuration of the Mini-CERTEC

measuring cell

1 Process diaphragm

2 Glass joint

3 Base element

A temperature sensor in the electronics of the Mini-CERTEC

meas-

uring cell measures the current process temperature. The tempera-

ture value is e.g. output via Bluetooth.

Relative pressure

: the measuring cell is open to the atmosphere.

The ambient pressure is detected in the measuring cell and compen-

sated. It thus has no influence on the measured value.

Absolute pressure

: the measuring cell contains vacuum and is

encapsulated. The ambient pressure is not compensated and does

hence influence the measured value.

The recessed installation is particularly suitable for applications with

gases, vapours and clear liquids. The measuring cell seals are posi-

tioned laterally as well as in front.
