The aircraft RPM Sensors we refer to in this article are the ones used to measure RPM of the Bendix Magneto or the Slick Magnetos. There's also the Dual Magneto but the popular ones in use are the Bendix Magnetos and the Slick Magnetos.

The Bendix Magneto is easily overhauled and therefore extremely cost effective. Companies such as J.P. Instruments manufacturers highly accurate aircraft RPM sensors for both - Bendix Magnetos and Slick Magnetos.

For the uninitiated, rather than rely on the aircraft battery, the power to the spark plugs comes from the magneto – think of it as a mini power generator. The Bendix Magneto is a small generator with a transformer, breaker switch and a distributor to guide the high voltage to the spark plugs.

A power generator obvious ... Read more »
