Abstract
A sensor system and method of operating the sensor system can include an indicator that is operable in resonance, the indicator being connected to a movable element of an actuator, and a sensor including sensor windings arranged in direct proximity to the indicator and external to a closed housing. The sensor can receive a position or an angle of the indicator, and can measure the position or the angle of the movable element inside the actuator through the closed housing based on inductive resonance facilitated by the indicator.
Claims21
A sensor system, comprising:
- at least one indicator comprising an oscillating circuit that is operable in resonance;
- the at least one indicator connected to a movable element of an actuator;
- and
- a sensor PCB comprising sensor windings, wherein the sensor PCB with the sensor windings are arranged in direct proximity to the at least one indicator and external to a closed housing, wherein the sensor PCB receives a position or an angle of the at least one indicator, and measures a position or an angle of the movable element inside the actuator through the closed housing based on inductive resonance facilitated by the oscillating circuit.
(canceled)
A sensor system, comprising:
- at least one indicator operable in resonance;
- the at least one indicator connected to a moveable element of an actuator;
- and
- a sensor comprising sensor windings, wherein the sensor with the sensor windings are arranged in direct proximity to the at least one indicator and external to a closed housing, wherein the sensor receives a position or an angle of the at least one indicator, and measures a position or an angle of the movable element inside the actuator through the closed housing based on inductive resonance facilitated by the at least one indicator.
