The new GE200 HP is a non-contact electromagnetic inductive sensor designed for making RPM measurements on gasoline engines. The sensor will detect the high voltage flux field being induced from ignition coils or magnetos on 2 or 4 cycle gasoline engines. The GE200 HP must be connected to the Monarch amplifier module which provides input power and a TTL pulse output. The GE200 HP includes an integral 15 foot (5 m) cable that can be extended to 150 feet (50 m).

The GE200HP sensor can be mounted up to 12 inches (30 cm) away from the ignition coil or magneto. The sensor will detect the electromagnetic flux field through metal engine covers. To find the optimal mounting position, simply move the sensor around the high voltage flux source until the display on your tachometer indicates a steady RPM reading.
