WayCon has developed the SX300 especially for stroke measurement of hydraulic and telescopic cylinders up to 15 m stroke for flange-mounting to the cylinder face. The extremely robust sensor is designed for operating pressures up to 300 bar. The measuring cable running in the cylinder is simply attached to the piston and held taut by a spring in the sensor, regardless of the piston position. The sensor element, a digital encoder is located outside the pressure range and provides information about the position of the piston with the highest accuracy and resolution. The stroke measurement of hydraulic weir gates, or the synchronization monitoring of parallel cylinder arrangements are classic applications for the SX300.
