VEGABAR 81

Pressure transmitter with chemical seal

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

  • Adaptação fácil devido às diversas possibilidades de configuração
  • Medição segura com temperaturas de até 400 °C
  • Medição confiável, independentemente da formação de espuma e de anteparos no tanque

Pressure transmitter with chemical seal for hot and chemically aggressive media

The pressure transmitter VEGABAR 81 with chemical seal system demonstrates its capability especially in high temperatures and aggressive media. A wide range of diaphragm materials and coatings make this pressure transmitter an essential instrument across many sectors, particularly in  the chemical and petrochemical industries. 
The pressure transmitter with chemical seal delivers reliable measurement data for feedback control systems or protective equipment, e.g. for
  • continuous monitoring of process pressure in reactors 
  • exhaust pressure of flue gas, e.g. in waste incineration 
  • pipeline pressure in dairies 
  • steam pressure control in steam drums 
  • pressure monitoring in LNG tanks
