Orange Research”s Class 1, Div. 1-rated piston and diaphragmdifferential pressure sensors can be safely operated where flammablegases or vapors often exist because of their robust, sealedenclosures. The switches and electrical connectors in these unitsare housed in UL, CSA, FM, and ATEX-approved enclosures. Theepoxy-coated, cast aluminum enclosures have two mounting lugs, two 3/4″NPT electrical conduit ports, and meet Class 1, Gr. B, C, and D; Class2, Gr. E, F, and G; and Class 3 specifications. They also meet NEMA 3,4X, 7, 9, and 12 specifications. Explosion-proof differential pressureinstruments are available in gauge, switch, and transmitter versions inpressure ranges from zero to five inches of water to zero to 300 PSID,and maximum line service is up to 5,000 PSIG. Optional field-adjustablereed switches control alarms and processes.
