Patent ID: 7493195

Claim:
A fluid regulation system, the system comprising: a pressure cavity operable to receive a pressure supply for generating a pressure signal for controlling a fluid regulator; an electric-to-pressure converter comprising: a wire coil operable to be energized according to a control signal, a magnetizable element movable relative to the wire coil in response to the energy in the wire coil, the position of the element affecting the pressure in the pressure cavity to generate the pressure signal; a pressure sensor coupled to the pressure cavity and operable to sense the pressure in the pressure cavity due to the position of the magnetizable element and to generate a signal representative thereof, the pressure in the pressure cavity comprising a first sensed parameter of the fluid regulation system, and a controller coupled to the wire coil and the pressure sensor, the controller operable to: generate the control signal in response to a received command signal, and adjust the control signal based on the pressure sensor signal and the received command signal; a second sensor operable to sense a second parameter of the fluid regulation system and to generate a signal representative thereof; and a processor coupled to the electric-to-pressure converter and the second sensor, the processor operable to: generate the command signal, and adjust the command signal based on the second sensor signal.
