Type 711.12, Copper Alloy Wetted Parts, Type 731.12, Stainless Steel Wetted Parts
Applications
DesignTwo independent measuring systems, parallel in-line pressure entry
Sizes4" & 6" (100 mm & 160 mm)
Accuracy+ 1.5% of full scale value
RangesPressure from 10 psi (0.6 bar) to 15,000 psi (1,000 bar)Scale range must be selected based on the highest working pressure applied. The pressure differential to be indicated should be no less than 1/6 of the full scale range. When ordering please state both the max working pressure applied and the differential to be indicated.
Working RangeSteady: full scale valueFluctuating: 0.9 x of full scale valueShort time: 1.3 x full scale value
Operating TemperatureAmbient: -4°F to 140°F (-20°C to 60°C) 1,000 psi (70 bar)Media: max. 140°F (+60°C) max. 212oF (+100oC) - 1,000 psi (70 bar)
Temperature ErrorAdditional error when temperature changes from reference temperature of 68°F (20°C) +0.4% of span for every 18°F (10°K) rising or falling.
Weather ProtectionWeather resistant (NEMA 2 / IP 33)
