ABSTRACT:
A pressurized gas system controls a gas flow from one or more gas pressure storage vessels by means of an electronically controlled electro-mechanical shut-off valve located in close proximity to each of the vessels. The shut-off valves are electrically wired to actuation switches on the control panel. Pressure transducers mounted on each vessel provide a signal output which is electrically connected to a digital numeric display located on the control panel so that the pressure of each vessel can be monitored. Gas flow from the vessels is controlled by means of the electric shut-off valves operated from the control panel. A pressure regulator at the air access station controls the final output pressure delivered to the tool or personnel air bottle. Thus, the vessel pressures may be monitored without pressurized lines running between each vessel and the control panel and the mechanical liquid filled dial-type gauges typically used are replaced with digital numeric read-outs which are more reliable and self-illuminating.
