Description
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

0 … 25 mbar to 0 … 25 bar absolute pressure
Pressure limitation
Steady: Full scale value
Fluctuating: 0.9 x full scale value
Overload 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
