Abstract
A dual compartment housing has a wiring compartment containing customer accessible wiring board and openings for a conduit connection. The wiring compartment is separated from an electronics compartment by a tunnel. The tunnel, which can be potted with a sealing compound, provides environmental and explosion proof protection for the electronics. An intrinsically safe barrier can be housed in the explosion proof wiring compartment, and the electronics compartment is then intrinsically safe. This relieves any constraint on separating the intrinsically safe electronics exposed to the process by an explosion proof boundary, and the process seal can be a 'soft' seal. The housing is designed so that both compartments face the same direction.
