The Silversmith Data SIDPG is a Class1 Div2, a low-cost multivariable sensor that can measure differential and gauge pressure from the same sensor body. The differential sensor has a scale of 0-200 inches of water. The gauge sensor has a scale of 0 – 100 PSIg with a maximum unit working pressure of 100 PSIg. The unit features an internal temperature correction for accuracy of +/- 1% of full scale. The NEMA 4x house is designed for outdoor use. SIDPG is ideal for metering low-pressure natural gas.
