With chemical seal, for high temperatures
|
|
Application area
Reliable measurement of highly corrosive and hot media. Can be combined with any other sensor of VEGABAR Series 80 for electronic differential pressure measurement.
The VEGABAR 81 is a pressure transmitter with chemical seal for pressure and level measurement. The chemical seal systems of VEGABAR 81 adapted to the process, ensure a reliable measurement even with highly corrosive and hot products. The simple connection of VEGABAR series 80 sensors as electronic differential pressure opens new possibilities for the measurement of differential pressures.
Your benefit
- Simple adaptation thanks to various configuration options
- Reliable measurement with temperatures up to 400 °C
- Reliable measurement independent of foam generation or tank installations
