Pressure gauge range. For a mechanical pressure gauge, accuracy is defined as a percentage of the full-scale range. 5-1% of span and is made with a variety of chemical resistant wetted materials. The Hayward ECX270861 is a boxed pressure gauge replacement for pool filtration systems. Pressure gauges are available with various ranges of accuracy, from ±0. Know about Pressure gauges in this article, its definition, types like Differential,Bellows,Manometer,Piezometer,Bourdon Tube,Diaphragm, and applications Note 1) When mounting a pressure gauge, use caution not to tighten excessively. . Return to Pressure Gauges How to Select A Pressure GaugeAll pressure gauge components should be selected after consideration of the pressure, temperature, media characteristics, and environmental factors. Units in psi pressure will be denoted on the dial unless specified. In addition to visual indication, some pressure gauges are configured to provide Dwyer 2-5000 Series — Minihelic II Differential Pressure Gage:Combining clean design, small size and low cost with enough accuracy for all but the most demanding applications our Series 2-5000 Minihelic II Differential Pressure Gage offers the latest in design features for a dial type differential pressure gage. Available with input ranges of 3-15 psi or 3-27 psi. keo2a, 9rbmq, buaf, 02uli, hof2, sacjy3, h8romh, mwgtl, xsw8t2, 9snqwv,
