Sensing Linear Position in Telescoping Hydraulic Cylinders

Telescoping Hydraulic Cylinders find uses in everything from raising the bed of a dump truck, to the massive riser tensioner cylinders used on offshore oil rigs. Telescoping cylinders were first designed to provide long stroke lengths where the total length required would not fit in into the machine. Instead these cylinders are multi-stage and their construction presents challenges for accurate and reliable position sensing, especially in harsh environments.
