Mini-Gen® Signal Generators

The Mini-Gen® Signal Generator develops an AC sine wave that can be used to measure the speed of rotating machinery or engine RPM. Most notably, the Mini-Gen is used on over-the-road vehicles where the input is sent to either a tachometer or a speedometer for determining vehicle speed.
