These Explosion-Proof Enclosures are a safe and rugged way to mount digital panel meters in hazardous locations. One or two meter configurations are available. One 3/4" NPT conduit hole is standard. Two or more conduit holes are available by special order. The 2" pipe mounting kit model PDA6545 is available for the PDA2444, PDA2445, and PDA2446 Explosion-Proof Enclosures. The Explosion-Proof Control Stations can be used with explosion-proof meters or with digital panel meters that are mounted in explosion-proof enclosures. These Explosion-Proof Control Stations contain either 1, 2, or 3 switches that can be connected to terminals on Precision Digital meters to control various functions. Enclosures, accessories, and meters are ordered separate.
