Abstract
An intrinsically safe microprocessor controlled pressure regulator for operation in a hazardous environment. The intrinsically safe microprocessor controlled pressure regulator receives control commands that are input to a microprocessor in the hazardous environment. The microprocessor generates control commands to control operation of an intrinsically safe solenoid valve and an intrinsically safe piezo electric valve. The piezo electric valve generates an output signal for controlling operating parameters of the paint gun. One or a plurality of microprocessors may operate within a hazardous environment in order to control one or a plurality of intrinsically safe valves in the hazardous environment.
