By using rotation speed of an alternator, the rotation speed of the engine can be measured regardless of engine types and number of cylinders.
The rotation speed ratio between the alternator and engine is required to calculate the engine rotation speed. Calibration must be executed before measurement to find the rotation speed ratio.
Possible to measure while driving
High noise tolerance and stable measurement
It may not be measured depending on the engine and motor type. For more details, please contact your nearest distributor or send us an e-mail: overseas@ONO SOKKI.co.jp)
To use the GE-2500, the alternator and engine must be running in synch with each other. The measurement error may become large when the special kind of alternator is used or the belt between the alternator and engine is loose.
