Differential Pressure Gauges with Bourdon Tube, Parallel Entry (Price & availability on application)

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 ... 1,000 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 52
