Abstract:
A linear position sensor having a transmitter coil which generates electromagnetic radiation when excited by a source of electrical energy and wound in a first direction. A receiver coil is contained within the transmitter coil and the receiver coil includes both a first loop wound in a first direction and a second loop wound in the opposite direction. A coupler element linearly moves along a first direction relative to the transmitter coil which varies the inductive coupling between the transmitter coil and the receiver coil as a function of the linear position of the coupler element to thereby vary the electrical output signal from the receiver coil when excited by the transmitter coil. The first and second loops of the receiver coil are linearly aligned with each other along the first direction.
