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.
