Signaling wheel kit for electronic fuel injection system for monitoring position of crankshaft in automobile industry, has sensitizer ring reloaded during operation, where kit includes static device for reloading ring during operation

摘要

The kit has an electrified sensitizer ring (1) mounted around a rotary part (100) to be monitored, and a sensor (20) mounted closer to the sensitizer ring. A sensitizing unit (40) integrates between the sensitizer ring and the sensor for generating electrical signals, and an electrical circuit (60) processes a signal (21). The sensitizer ring generates an electrical field in a position, includes an electrical start load, and is reloaded during operation, where the kit includes an electro static device (80) for reloading the sensitizer ring during operation.
