DesignTwo independent measuring systems, vee entry 60°
Nominal size in mm100, 160
Scale ranges0 ... 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 limitationSteady: 3/4 x full scale valueFluctuating: 2/3 x full scale valueShort time: full scale value
Operating temperatureAmbient: -20 ... +60 °CMedium: +60 °C maximum
Temperature effectWhen the temperature of the measuring system deviates from the reference temperature (+20 °C):max. ±0.4 %/10 K of full scale value
