Abstract
A pickup probe for engine timing which is responsive electrically to an indicator on a rotating engine part. The free end of the probe is adapted to extend through an access opening in an engine member into proximity with the indicator on the rotating engine part. A sensor is contained within the free end portion of the probe. The probe includes a mounting means adapted to be detachably secured to the engine member adjacent the aforesaid access opening. The free end of the probe has limited longitudinal movement with respect to the mounting means so as to accommodate dimensional irregularities in the engine and enable the free end of the probe to be moved in adjusting manner to a selected longitudinal position with respect to the rotating part indicator to establish an effective air gap, and means are provided to maintain the free end of the probe in the selected position, thereby insuring continued proper spacing of the sensor and indicator by the effective air gap and the generation of timing signals of high quality for processing in associated equipment.
