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

Description of the absolute pressure gauge

Nominal size in mm
100, 160

Accuracy class
Model 532.52: 1.0
Model 532.53: 1.6
Model 532.54: 2.5
The measuring accuracy is ensured for fluctuations in atmospheric pressure between 955 and 1,065 mbar (min. and max. of atmospheric pressure).

Scale ranges
0 ... 25 mbar to 0 ... 25 bar absolute pressure

Pressure limitation
Steady: Full scale value
Fluctuating: 0.9 x full scale value

Overpressure safety
Minimum 1 bar absolute pressure (atmospheric pressure), in addition 10 x full scale value, max. 25 bar absolute pressure

Permissible temperature
Ambient: -20 ... +60 °C
Medium: +100 °C maximum

Temperature effect
When the temperature of the measuring system deviates from the reference temperature (+20 °C):
max. ±0.8 %/10 K of full scale value

Ingress protection
IP54 per IEC/EN 60529
