Diesel Engine Tachometer
GE-2500 - Ono Sokki
The GE-2500 diesel engine tachometer uses rotation speed of an alternator to measure engine rotation speed. With FFT calculation, this tachometer achieves reliable and stable measurement for both diesel and gasoline engines.
The OM-1500 is a compact type detector designed for measuring rotation speed of an alternator. It detects magnetic flux leakage from an alternator. It is used to combine with the GE-2500. (The OM-1200 can also be used with the GE-2500.)
