Position detection in hydraulic cylinders

The patented SX200 is one of the few Draw Wire Encoders that can be integrated into hydraulic cylinders and can measure a stroke of up to 12m. No other measurement principle reaches this measuring range without removing the cylinder, with a simultaneous integration of the measuring system.

Due to the way the hydraulic cylinder is assembled, the entire measuring system is optimally protected. The SX200 is remarkably suited to application in confined spaces. The measuring cable is connected to the piston and is pulled from the sensor during the operation of the cylinder.

In the sensor itself, the measuring cable is coiled around a cable sheave, which rotates with each cylinder stroke, thereby turning the linear movement into a rotation. Through a sealed shaft (pressure implementation) the rotary movements are directed outwards into an unpressurized area and recorded by a sensor element (e.g. a digital absolute rotary encoder).

Through the evaluation of sensor signals, not only is the position of the piston rod regulated, but the specific cylinder positions are also recorded and the synchronic movement of multiple cylinders is ensured. The highly dynamic sensors also allow for rapid cylinder movements during this process.

The compact casing, as well as adaptation to customer needs, qualify this sensor technology for multiple areas of application. Thanks to its robust construction and high quality, the sensor can be employed in harsh industrial environments.

Typical applications for the Draw Wire Encoder SX200 are: Hydraulic gates on dams; monitoring of simultaneously running cylinders; regulation and monitoring of traverse speed.
