Abstract
A gas monitoring and oxygen supply control system, including a flame-proof and explosion proof housing; a gas monitoring sensor system enclosed in said housing, said sensor system including a sensor controller, a plurality of gas sensors, and a CPU; air sampling pipes in fluid communication with said gas sensors and with the atmospheres to be sampled; input sampling ports disposed on said air sampling pipes and exposed to the atmospheres to be sampled; at least one exhaust pipe for venting gases to a select atmosphere outside said housing; flame-proof port assemblies disposed through a wall of said housing separating said sensor system from an outside atmosphere and through which said air sampling pipes and said exhaust pipe are disposed; at least one pump operatively connected to said air sampling pipes so as to provide both suction and exhaust, said pump electronically connected to and controlled by said CPU; a plurality of valves disposed on said air sampling pipes and electronically coupled to and controlled by said CPU; and a transceiver coupled to said CPU and to a feedthrough radio antenna disposed through a side of said housing for communicating bi-directionally with one or more handsets.
