VEGABAR 87 • Modbus and Levelmaster protocol

46297-EN-220624

Fig. 3: Level measurement with VEGABAR 87

The process pressure acts on the sensor element via the stainless

steel diaphragm and an internal transmission liquid. The process

pressure causes a resistance change which is converted into a cor-

responding output signal and output as measured value.
The METEC

measuring cell is the measuring unit. It consists of

the ceramic-capacitive CERTEC

measuring cell and a special,

temperature-compensated isolating system.
