Positioning Hall sensor relative to ferromagnetic stop for adjusting ignition distributor - exciting sensor to oscillate and measuring intensity of oscillation during relative motion until threshold reached

摘要

The method involves moving the sensor and stop w.r.t. each other until the Hall voltage reaches a certain value, whereupon they are locked w.r.t. each other. The Hall sensor is stimulated to oscillate by feeding a clocked operating current to it. The intensity of the oscillation is measured by an analogue measurement device during the relative motion and the locking is performed when a defined intensity level is reached. The clock frequency is approximately 350 Hz. USE/ADVANTAGE - Esp. for adjusting the ignition distributor of internal combustion engine. High reliability.
