3.2 Principle of operation

VEGABAR 52 is a pressure transmitter for use in the paper, food

processing and pharmaceutical industries as well as in water/sewage

water plants. Depending on the version, it is used for level, gauge,

absolute pressure or vacuum measurement. Measured products are

gases, vapours and liquids, also those containing abrasive sub-

stances.

Sensor element is the CERTEC

®

measuring cell with robust, depend-

ent on the process fitting also front-flush, abrasion-resistant ceramic

diaphragm. The process pressure causes a capacitance change in

the measuring cell via the ceramic diaphragm. This change is con-

verted into an appropriate output signal and outputted as measured

value.
The CERTEC

®

measuring cell is also equipped with a temperature

sensor. The temperature value can be displayed via the display and

adjustment module as well as processed via the signal output (with

digital versions).

As a standard feature, the CERTEC

®

measuring cell is equipped with

a lateral, recessed seal.
