Abstract
A piston assembly includes a housing, a piston positioned within the valve housing, and an inductive proximity probe sensor positioned on the housing configured to detect a position of the piston with the housing. The piston is configured to at least one of rotate or translate axially relative to the housing. The piston includes a variable surface. A fuel control system includes the piston assembly, a servo valve in fluid communication with the piston assembly, and an engine controller. The engine controller is operatively connected to the inductive proximity probe sensor.
