Slip Detector
By detecting the real-time speed of the driven pulley of the belt conveyor, the slip detector can determine whether a conveyor belt slip fault exists, and issue two-stage alarm signals in time based on speed variations to prevent losses and the expansion of accidents. This product adopts advanced ARM processor technology and embedded control principles, featuring stable performance, powerful functions, and a high protection rating.
The premium Xieli heavy-duty Slip Detector (Model: XLDH-F-III) is purpose-engineered to survive extreme industrial environments. Primarily deployed in large-scale belt conveying systems across mining, steel metallurgy, port terminals, and power stations, this machinery guarantees maximum operations protection. Fully compliant with state-level flameproof and explosion-proof requirements, it operates securely with structural integrity under heavy debris and moisture overload.
