Differential Pressure Gauges with Bourdon Tube, Parallel (Price & availability on application)
SKU:
press-product31
Design
2 independent measuring systems, parallel entries in line
Nominal size in mm
100, 160
Accuracy class
1.6
Scale ranges
0 ... 0.6 to 0 ... 1000 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: full scale value
Fluctuating: 0.9 x full scale value
Short time: 1.3 x full scale value
Operating temperature
Ambient:
-20 ... +60 °C
Medium:
Model 711.12: +60 °C maximum (soft soldered); +100 °C maximum (brazed)
Model 731.12: +200 °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
