Accurate and powerful ground speed sensors.

Measuring ground speed has never been easier than with DICKEY-john high-performance ground speed sensors.

Accurate speed sensing enables you to achieve top performance from your electronic monitoring and controlling products. An incorrect speed signal can potentially provide substantial errors in speed and distance measurement, chemical and fertilizer application and yield calculations. All of that can lead to expensive misapplications, crop damage, and reduced yields.

The DICKEY-john Radar II delivers the truestvelocity measurement at mounting heights over 96 inches (243.8 cm).  The high-performance, top-of-the-line Radar III ground speed sensor is a streamlined, more compact version of DICKEY-john’s best-selling  Radar II model.

The true ground speed sensors calculate speed independently of wheel motion using a microwave (radar) signal and the principle of Doppler shift (measuring the changes in the frequency of the reflected signal). Because they don’t use the movement of a wheel or drive shaft, errors in signal due to wheel slippage or wheel distortion from varying loads and ground conditions are eliminated.

The DICKEY-john radars may also be used to improve the performance of other monitors and control systems that require a speed sensor signal.
