Measurement example: Measuring rotation of an EV/HEV
Method1: Using magnetic flux leakage from a motor
Product list of Engine tachometer
A gasoline engine rotation is measured mainly by detecting ignition pulses. By improvement of an automobile performance in recent years, a sensor with high sensitivity is more and more required for the ignition pulse detection.

Detector for a gasoline and diesel engine/detector for a diesel engine
This type of sensor detects rotation mainly by the vibration different from the ignition pulse sensor which detects rotation by the ignition pulse. The diesel engine rotation detector CP-044 detects vibration caused by the reciprocating up and down movement of the engine’s piston at the time of fuel injection.
