3.2 Principle of operation

VEGABAR 66 4 … 20 mA/HART - climate compensated is a suspen-

sion pressure transmitter for level measurement in wells, basins and

atmospherically open vessels under dicult conditions (cold medium

and warm humid environment).

The sensor element is an encapsulated CERTEC

absolute pressure

measuring cell with robust, front-ush (depending on the process

tting), 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

signal, compared with an integrated reference pressure measurement

and outputted as measured value via the output signal.

The CERTEC

measuring cell is also equipped with a temperature

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

adjustment module or processed via the signal output.

As a standard feature, the CERTEC

measuring cell is equipped with

a lateral, recessed seal.

Instruments with double seal have an additional front seal.
