3.2 Principle of operation
VEGABAR 55 is a pressure transmitter for use in the chemical, food
processing and pharmaceutical industries. Depending on the version,
it is used for level, gauge, absolute pressure or vacuum measure-
ment. Measured products are gases, vapours and liquids, also those
with higher temperatures.
The METEC ® measuring cell is the measuring unit. It consists of
the ceramic-capacitive CERTEC ® measuring cell and a special,
temperature-compensated isolating system.
The hydrostatic pressure of the product or the process pressure
causes a capacitance change in the measuring cell via the metallic
process diaphragm and the isolating liquid. This change is converted
into a corresponding output signal.
