Intrinsically safe microprocessor controlled pressure regulator
First Claim
1. An intrinsically safe pressure control system for controlling operation of a device placed in a hazardous area, a portion of the control system operating in a safe area, and a portion of control system operating in the hazardous area, comprising:
- a controller located within the hazardous area, the controller receiving input signals from the safe area, the controller generating a control signal; and
a first piezo electrically controlled valve located within the hazardous area, the piezo electrically controlled valve generating an output pressure in response to the control signal.

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.
