The VEGA VEGABAR 81 Pressure Transmitter is designed for pressure and level measurement, and includes chemical seals adapted to the process to ensure a reliable measurement even in highly corrosive and hot products. 

The pressure measuring cell transforms the pressure into an electrical signal. This pressure-dependent signal is converted by the integrated electronics into a standardized output signal.

The VEGABAR 81 is provided with a completely welded chemical seal system with internal transmission liquid. For measuring ranges up to 40bar, a piezoresistive sensor element is used, from 100bar a strain gauge sensor element.
