YG11-830-20 two-stage deviation switch YG11-830-20 two-stage deviation switch YG11-830-20 two-stage deviation switch Application: Used to detect the deviation phenomenon during the operation of belt conveyors, output alarms or shutdown signals according to the actual deviation amount of the belt, and effectively prevent accidents caused by belt deviation. It is a protective device that realizes automatic alarm and shutdown of the tape machine control. The two-stage deviation switch is suitable for belt conveyors, which can issue an alarm signal and further automatically stop the belt conveyor before it can cause serious edge wear or even tear accidents due to belt deviation. Can timely and effectively protect equipment A's safety, avoid accidents from escalating, and achieve the goal of ensuring production and protecting equipment. In addition, since signals can be sent to the control system, it is convenient to achieve factory automation control, which can also achieve the goal of reducing staff and increasing efficiency, centralized control, and facilitating production and scheduling. The working principle is that the two-stage deviation switch is installed on both sides of the belt conveyor, 1-3 meters away from the front and rear ends of the belt conveyor. When the belt deviates, the edge of the belt presses against the gear wheel, forcing it to deflect and causing the limit switch to operate. To reduce friction between the gear wheel and the belt, the main body of the gear wheel is made of bearings. When a minor deviation accident occurs (12 °), the * group contacts of the two-stage deviation switch act and issue an accident warning signal. When a serious deviation accident occurs (30 °), the second set of contacts of the two-stage deviation switch will act, which can automatically stop the conveyor. Features: Simple and practical structure, stable and reliable performance, dust-proof, shockproof, moisture-proof, small size, light weight, long service life, easy installation, maintenance free. The output signal can be interlocked with on-site equipment and can also be delivered to microcomputer control systems. The power supply has wide adaptability: 24~380V explosion-proof intrinsic safety type with thermocouple resistance, SBWR-4270/440D, WZP2-892 indoor double platinum thermistors,
