Vegabar 81 Pressure Transmitter

Brand: VEGA
Request Information
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.
Features
  • Simple Adaptation, Thanks to Versatile Configuration
  • Reliable Measurement up to Temperatures of 400° C
  • Reliable Measurement Independent of Foam Generation and Tank Installations
