Two pole deviation detection device PWB-12-30 Two pole deviation detection device PWB-12-30 Two pole deviation detection device PWB-12-30 Scope of application Two level deviation switch is used for conventional belt conveyors: underground, cableway support belt conveyors: ship loading and unloading systems; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Crane, excavator, boom limit: skirt feeder/conveyor: heavy-duty limit switch detects the deviation of the tape, which is a protective device for automatic alarm and shutdown of the tape machine control. Widely used in various belt conveyor equipment in fields such as metallurgy, coal, cement and building materials, mining, electricity, ports, metallurgy, chemical industry, etc& lsquo;  During the operation of the conveyor, when the belt deviates and comes into contact with the switch vertical roller, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset.
