Abstract
A system for producing a signal as a function of a rotational speed of a wheel includes an exciter, which includes a plurality of teeth, secured to the wheel. A cover has a first end facing the exciter. An active sensing element is within the cover and positioned away from the first end of the cover by at least about 10% of a total length of the cover. The teeth pass by the first end of the cover and the active sensing element at a rate proportional to the rotational speed of the wheel. The active sensing element producing signals as a function of the rate the teeth pass the active sensing element. An air pocket within the cover maintains the active sensing element below a predetermined temperature.
