Belt position sensor DB-PL4868 two-stage deviation switch DB-PL4868 two-stage deviation switch: suitable for coal, metallurgy, chemical, grain, transportation and other industries, as well as coal preparation plants, steel plants, thermal power plants, grain depots, ports and other harsh ground environments, used for conveyor belt deviation detection and protection. Working principle of DB-PL4868 two-stage deviation switch: The working process of this switch is that when the conveyor belt deviates, the belt touches the switch vertical roller. When the vertical roller deviates to the first level action angle, the first level switch will act and output a signal alarm. If the tape continues to deviate and the vertical roller of the switch reaches the level II action angle, the level II switch will send a stop signal. If it is connected to the control circuit, automatic shutdown can be achieved. The high-temperature resistant deviation switch is suitable for high-temperature environments. This switch uses proprietary stainless steel high-temperature resistant material, and the power cord uses high-temperature resistant silicone wire. Scope of application: Two level deviation switch for conventional belt conveyors: underground, cable 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. Installation and adjustment: 1. The deviation switch should be set on both sides of the conveyor belt, and the vertical rollers should be perpendicular to the edge plane of the conveyor belt, with both sides of the conveyor belt located at 1/3 of the height of the vertical rollers. The distance between the vertical roller of the deviation switch and the normal position of the conveyor belt should be 50-100mm. The number of deviation switches should be determined based on the length, type, and layout of the conveyor. Generally, it should be set at the head, tail, convex arc section, concave arc section, and in the middle position of the conveyor. (Note: When the conveyor is long, one pair can be installed every 30-35 meters in the middle position of the conveyor.) 4. The deviation switch should be connected to the middle frame of the conveyor through an installation bracket. The switch bracket should be welded to the conveyor frame after the conveyor is installed. The deviation switch and the deviation switch bracket should be fixed with bolts< br/>
