Design
EN 837-3
Nominal size in mm
100, 160
Accuracy class
1.6
Scale ranges
0 ... 16 mbar to 0 ... 250 mbar (flange Ø 160 mm)
0 ... 400 mbar to 0 ... 25 bar (flange Ø 100 mm)
or all other equivalent vacuum or combined pressure and vacuum ranges
Pressure limitation
Steady: Full scale value
Fluctuating: 0.9 x full scale value
Overpressure safety
5 x full scale value, however max. 40 bar
Permissible temperature
Ambient: -20 ... +60 °C
Medium: +100 °C maximum
Storage: -40 … +70 °C (scale ranges ≤60 mbar: -20 ... +70 °C)
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 IECEN 60529
(with liquid filling Model 433.50) IP65)
