Differential Pressure Gauges with Bourdon Tube Element, Vee Entry

Differential Pressure Gauges with Bourdon Tube Element, Vee Entry

Two independent measuring systems, vee entry 60°

Nominal size in mm
100, 160

Accuracy class

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
