A Hall-effect linear-displacement transducer monitors piston rod position accurately on agricultural tillage equipment and provides precise control of tillage depth that increases crop yield, reduces fuel consumption, and minimizes wear on the implement and tractor.

Farmers need to break up compacted soil (known as hardpan) in their fields to promote root growth so crops can achieve the highest possible yield. For decades, farmers have achieved this by setting their tillage equipment to plow as deeply as possible to accommodate varying but unknown depths of the compacted soil. Now, with ground-penetrating radar and GPS technology, they can map the hardpan throughout their fields. To take advantage of this information and break up the hardpan efficiently, farmers need a way to achieve accurate, variable depth control on the fly.

A linear-displacement transducer designed and manufactured by Rota Engineering Ltd., headquartered in Bury, Manchester, UK, uses linear Hall-effect to achieve the accuracy needed for agricultural applications in a package that can withstand the shock, vibration, and ambient conditions of plow equipment. The transducer mounts inside a hydraulic cylinder and is straightforward enough that it can be installed by the cylinder manufacturer, equipment manufacturer, or a dealer.
