Rated Class 1, Div. 1, this line of piston and diaphragm differential pressure sensors is suitable for applications that involve flammable gases or vapors. The devices feature sealed enclosures said to be robust in construction and UL, CSA, FM, and ATEX approved. The epoxy-coated, cast aluminum enclosures, which feature two mounting lugs and two 3/4-in. NPT electrical conduit ports, meet Class 1, Gr. B, C, and D; Class 2, Gr. E, F, and G; and Class 3 specifications. They also meet NEMA 3, 4X, 7, 9, and 12 specifications. Engineers can choose explosion-proof differential pressure instruments in gauge, switch, and transmitter versions. Pressure ranges are available from 0 to 5 in. of water to 0 to 300 psid. Maximum line service is up to 5,000 psig. Optional field-adjustable reed switches can be used to control alarms and processes.
