Single geartooth sensor yielding multiple output pulse trains

摘要

A magnetic effect sensor system has a target with a first set of regularly spaced tooth/slot transition target features and a second set of different tooth/slot transition target features interspersed within the regularly spaced features. The mix of target features allows a single magnetic effect sensor to output a clocking pulse train for misfire detection and an encoded pulse train for determining absolute mechanical position by utilizing two thresholds on the sensor output waveform.
