Robust, simple, precise – the Draw Wire Sensor SX 300

With the SX 300, WayCon offers cylinder manufacturers a low-cost and easy-to-install way to measure the piston stroke of large cylinders

With the SX 300, WayCon Positionsmesstechnik has developed an extremely robust draw wire sensor especially for stroke measurement in hydraulic and telescopic cylinders. With a measurement range of up to 15 metres, the SX 300 is ideal for use in “large applications”, for example dams, sluice gates, drawbridges, cranes or when constructing wind turbines.

Thanks to its pressure-proof casing, the SX 300 can be mounted directly on the face of the cylinder. The stainless-steel measuring rope is simply attached to the piston and held tightly by a spring in the sensor. The sensor element, a digital encoder, is located outside of the pressure area and provides data about the position of the piston with the utmost precision and resolution. The output signals can be freely selected from SSI, Profibus, CANopen, Profinet or EtherCAT and therefore offer maximum flexibility in the selection of control concepts.

The dynamic and robust sensors also allow for fast cylinder movements, are designed for operating pressures of up to 300 bar and are suitable for ambient temperatures of -20°C to +70°C. As a consequence, and thanks to their reliability, they can be used in all industrial sectors. Traditional applications include, for example, stroke measurement of hydraulic weir gates or synchronisation monitoring of parallel cylinder arrangements.
