WB61 tape extension sensors measure strokes to 4 m, yet feature a compact housing. They provide three analog and three digital outputs (SSI, CANopen, CAN, SAE J1939), the option of redundant design, and nonlinearity of ±0.10%. They work best where multiple pulleys are required. Stainless steel measuring tape is not liable to break when using several pulleys, for adherence to strict safety requirements for cranes. Tape also resists fluctuating temperatures.
