Two independent measuring systems, parallel entries in line
Nominal size in mm
80, 100
Accuracy class
1.6
Scale ranges
0 ... 2.5 to 0 ... 60 bar -1 ... 0 ... +25 bar
-1 ... 0 ... +12 bar -1 ... 0 ... +30 bar
-1 ... 0 ... +15 bar -1 ... 0 ... +35 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
| Applications | 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 |
