THP-12-30 waterproof deviation switch THP-12-30 two-stage deviation switch is 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. Working principle: When the running tape deviates, the edge of the tape drives the vertical stick to rotate and squeeze to tilt. If the tilt angle of the vertical stick is greater than the action angle, the switch sends out a set of switch signals. If the vertical stick continues to tilt more than the second level action angle, another set of switch signals is output. Two sets of switch signals can be used for alarm or shutdown respectively. After the tape machine is reset and operates normally, the vertical stick will automatically reset. Structural characteristics: Made of aluminum alloy die cast shell, with high strength and light weight; The switch adopts imported travel switch, with large contact capacity, sensitive action, and long service life. Good sealing performance, with advantages such as dustproof, shockproof, and anti-corrosion, can be used for detecting conveyor belt deviation, preventing material overflow and other faults caused by belt deviation.
