1 Pressure Switches Differential/Dual Stage, G lass 90 / Refer to atalog 90T901 Differential Pressure Switch Differential pressure switches monitor the change in the difference between two pressures. G differential pressure switches are used in applications to signal that a predetermined pressure difference has been reached as a result of a widening or increasing difference between the two pressures. They can also signal that a predetermined pressure difference has been reached as a result of a narrowing or decreasing difference between the two pressures. 90GGW1 Table 22.2: NE 4, 4, 13 Enclosures UL Listed and S ertified s Industrial ontrol Equipment a Working Pressure Range on Decreasing (upper) ctuator djustable Difference on Decreasing Pressure (adds to working pressure) (lower) ctuator djustable Differential ctuates on Increasing Pressure (adds to adjustable difference) aximum llowable Pressure psi Single Pole Double Pole $ Price $ Price Diaphragm ctuated Nitrile (una-n) Diaphragm, Zinc Plated Steel Housing GGW GGW GGW GGW GHW GHW Piston ctuated #440 Stainless Steel Piston. #303 Stainless Steel Housing, Viton Fluorocarbon Diaphragm and O-ring, Teflon Retaining Ring GJW GJW GKW1 Dual Stage Pressure Switch G dual stage pressure switches are designed for use in applications where two separate pressure operations must be controlled by a single pressure monitoring device.
