3.2 Principle of operation
The VEGABAR 55 - climate compensated is a pressure transmitter
for use in the chemical, food processing and pharmaceutical industry
under difficult climatic 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 also with higher temperatures.
Measuring unit is the METEC ® measuring cell. This measuring cell
consists of the ceramic-capacitive CERTEC ® absolute pressure
measuring cell and a special temperature-compensated isolating
system. The process pressure causes a capacitance change in the
measuring cell via the ceramic diaphragm. This change is converted
into an electrical signal, compared with an integrated reference pres-
