Dust explosion-proof deviation switch FPI-20-35. Dust explosion-proof deviation switch FPI-20-35. Working principle of FPI-20-35 two-stage deviation switch. When the moving tape deviates, the edge of the tape drives vertical rotation and compresses to tilt the material. If the tilt of the vertical roller is greater than the first level action angle, immediately send out a set of switch signals; If the vertical roller continues to tilt more than the second level action angle, another set of switch signals will be output. The two sets of switch signals can be used for alarm or shutdown respectively. Introduction to the deviation switch: The deviation switch is used to detect the deviation and twisting degree of the tape machine. It can prevent damage to the edge of the belt and material detachment caused by the deviation of the tape. It is a protective switch that achieves automatic alarm and shutdown. Technical parameters: Temperature: -40 ℃~+60 ℃ Working pressure: 80~110kpa Electrical lifespan switch action: 100000 times deviation switch function: When the running tape deviates, the edge of the tape drives the vertical rod to rotate and squeeze to tilt. If the tilt angle of the vertical rod is greater than the first level action angle, the switch will generate a set of switch signals. If the vertical rod continues to tilt more than the second level action angle, another set of switch signals will be output. Two sets of switch signals can be used for warning or shutdown, the tape machine can reset and operate normally, and the upright rod can automatically reset.
