Explosion proof two-stage deviation switch EXKPT1-DP-20-35 explosion-proof two-stage deviation switch EXKPT1-DP-20-35 explosion-proof two-stage deviation switch, also known as mining two-stage deviation switch, is mainly used in underground coal mines, cement plants, power plants, coal preparation plants and other places with gas and dust particles. It is used for detection, alarm, and automatic correction of conveyor belt or belt deviation accidents. The switch has two action signals, and the first action signal is used for alarm of conveyor belt deviation. When the edge of the belt is detected to deviate by 12 degrees from the original position, the switch sends an accident alarm signal. If the conveyor belt continues to deviate, and the deviation angle reaches 30 degrees, the switch will force the cam inside the machine to rotate, causing confusion. Emergency stop signal for accidents, achieving the purpose of protecting the conveyor from accidental damage. The entire process is automated and does not require manual operation, Safe and simple, with strong reliability, it has been widely used in various types of conveying equipment such as conventional belt conveyors, inclined conveyors, shuttle conveyors, packaging production lines, belt conveyors, underground cable support belt conveyors, and has become a sensing element for conveyor automation control.
