Applications
Measurement of differential pressures or of two different
pressures applied
For gaseous and liquid media that are not highly viscous or
crystallising and will not attack copper alloy parts
Heating, ventilation and air conditioning
Special Features
Differential pressure with moving dial
Cost-effective and reliable
Scale ranges from 0 ... 0.6 bar
Description
Design
Two independent measuring systems, vee entry 60°
Nominal size in mm
100, 160
Accuracy class
1.6
Scale ranges
0 ... 0.6 to 0 ... 60 bar
Scale range must be selected in relation to the highest
total pressure applied! In heating plants with circulating pumps, the overall
pressure is usually defined as equal to the hydrostatic pressure plus the pump
pressure.
In order to ensure a good readability, the pressure
differential to be indicated should be no less than 1/6 of the full scale range.
When ordering please state both pressures:
a) maximum pressure applied,
b) differential pressure
Pressure limitation
Steady: 3/4 x full scale value
Fluctuating: 2/3 x full scale value
Short time: full scale value
Operating temperature
Ambient: -20 ... +60 °C
Medium: +60 °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
Ingress protection
IP 33 per EN 60 529 / lEC 529
