SIKO has recently developed hand-in-hand with its customers new wire cable sensors that, in combination with safe control systems, allows the overall system to be certified in pursuant to SIL2 PLd. With MTBF values of >100 years, these sensors can be used in certified complete systems.
The wire-actuated encoders SG32, SG42 and SGP/1 provide this enhanced security by a specialized and fully redundant sensor system, which is used to exactly determine the position. Two completely separate sensor systems detect the exact position and display them separately as analog signals. With measuring lengths between 3 m and 6 m, these sensors are ideally suited for accurate position determination of outriggers on cranes and working platforms as well as for determining the position of booms. Furthermore, the durable structure of the sensors is even more impressive, especially for mobile applications. Thus the spring assembly is protected against the ingress of dirt and water and always works perfectly even at temperatures below the freezing point.
