VEGABAR 86 (Secondary Sensor)


The VEGABAR 86 Secondary sensor is a submersible pressure transmitter which is combined with a sensor from the VEGABAR 80 series to produce an electronic differential pressure measurement. It is suitable for the measurement of the gauge difference, level with superimposed pressure or vacuum, flow, density or interface. The flexibility through different cable and tube versions, offers the possibility to use the VEGABAR 86 SecondarySensor in many applications. The simple connection of VEGABAR series 80 sensors as electronic differential pressure opens new possibilities for the measurement of differential pressures.

Application area

For level measurement in wells, basins and open tanks. Maximum sensor length: Cable 250 m, tube 6 m. Can be combined with any other sensor of VEGABAR Series 80 for electronic differential pressure measurement.

Your benefit

  • Low maintenance costs thanks to wear-free ceramic measuring cell
  • High plant availability through maximum overload and vacuum resistance of the ceramic measuring cell
  • Self-cleaning effect through front-flush installation

Submersible pressure transmitter for level measurement of water, acids and alkalis

Specially optimized for measurement of water, alkalis, acids and other chemically aggressive liquids, the submersible pressure transmitter VEGABAR 86 with ceramic measuring cell finds application in a wide range of industries – from water level measurement in the wastewater sector to level measurement in the chemical industry or in food production.
