GAC Magnetic Pickup Sensors

GAC Magnetic Pickup Sensors are an integral part of an electronically-governed system

Magnetic speed sensors attach to the flywheel casing and detects when ring gear teeth pass the tip of the sensor. Electrical impulses are produced by the sensor’s internal coil and feed back to the speed control unit, so engine performance can be monitored and adjusted.

GAC’s magnetic pickups are rugged and economic speed sensors. Sturdier than plastic sensors and outperforming semiconductor-type devices at high temperatures, GAC’s encapsulated sensors are unaffected by dust and dirt. Multiple sizes (in both U.S and metric threads) and configurations are available. Wire leads, military connectors, automotive connectors or stud terminals are also available.

Why should I switch to electronic governing?

The GAC range of electronic governing systems make it simple to get maximum productivity from your engines and gensets.

With electronic governing:

  • Gensets maintain a constant frequency whatever the load. Sensitive electronic equipment is protected against damaging fluctuations. This is especially important in IT and healthcare.
  • Engines respond faster to load changes – as much as 200 times faster.
  • You improve your fuel economy because an electronic governor accurately sets the engine’s throttle to match the load. That reduces your bills and also your environmental footprint.
  • You avoid the massive disruption of installing a new engine from scratch.
