Abstract
A railroad car wheel transducer includes a coil positioned along a rail of a track. The presence of a wheel proximal to the coil causes basic electrical characteristics of the coil, such as its inductance and Q factor to change, which is sensed and used to generate a coil signal. A calibrating circuit monitors the coil characteristics to compensate for long term drifts.
