Absolute pressure gauge, stainless steel High overload safety

Applications of the absolute pressure gauge

  • Pressure measurement independent of fluctuations in the atmospheric pressure
  • For gaseous, liquid and aggressive media, also in aggressive ambience
  • Monitoring of vacuum pumps
  • Control of vacuum packing machines
  • Monitoring of condensation pressures and determination of the vapour pressure of liquids


Special Features of the absolute pressure gauge

  • High overpressure safety
  • Long service life due to metallic media chamber sealing
  • Media chamber protected against unauthorised intervention, DT-GM 86 08 176
  • Gauges compatible with switch contacts
  • Scale ranges from 0 … 25 mbar absolute pressure
