DatasheetApplications
- Measurement of differential pressure or of two different pressures applied in refrigeration plants or compressors
- Simultaneous measurement of the vapour pressure and the resulting vapour temperature
- For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience

Scale ranges
0 … 2.5 to 0 … 60 bar -1 … 0 … +25 bar
-1 … 0 … +12 bar -1 … 0 … +30 bar

Other scale ranges on request
In order to ensure a good readability, the differential pressure should be no less than 1/6 of the full scale value.
When ordering state both pressures:
a) maximum total pressure applied, b) differential pressure
Pressure limitation
Steady: Full scale value
Fluctuating: 0.9 x full scale value
Short time: 1.3 x full scale value
Permissible temperature
Ambient: 0 … +60 °C
Medium: +100 °C maximum
Temperature effect
When the temperature of the measuring system deviates from the reference temperature (+20 °C):
max. ±0.4 %/10 K of full scale value
