Apparatus and methods for determining a position of a movable component. One apparatus includes a controllable source (102) of varying magnetic flux. In a particular embodiment, the magnetic flux is directed through a magnetic sensor (120) using a first flux concentrator (115a) and a second flux concentrator (115b). The sensor (120) generates a sensor signal (126) that is provided to an electrical circuit (127) designed to demodulate the signal. The demodulated signal is provided to a controller (112). The controller (112) converts the signal and calculates the position of the second flux concentrator (115b) relative to the first flux concentrator (115a). The controller (112) may take a predetermined action based on the calculated position of the second flux concentrator (115b). |
