The XGuard Self-Calibrating Back Plate RPM Sensor with Static discharge protection and sensor power buffering is the most advanced Back Plate RPM Sensor to date.
The sensor works by sensing the magnetic field variation of the first pulses and calibrates itself to the ideal magnetic field trigger point for that particular engine. It adjusts the gain of the hall-effect amplifier to maintain a steady constant reference so the pulses are equal and symmetric.
