3.2 Principle of operation
VEGABAR 54 - climate compensated is a pressure transmitter for use
in the paper and food processing industries as well as in water/waste
water applications under difficult conditions (cold medium and warm,
humid environment).
Depending on the version, the pressure transmitter is used for meas-
urement of level, gauge pressure or vacuum. Measured products
are gases, vapours and liquids, including those containing abrasive
substances.
The sensor element is an encapsulated CERTEC ® absolute pressure
measuring cell with robust, front-flush (depending on the process
fitting), abrasion resistant ceramic diaphragm. The process pressure
causes a capacitance change in the measuring cell via the ceramic
diaphragm. This capacitance change is converted into an electrical
