Two stage deviation switch HFPK-III, also known as two-stage deviation switch. During the operation of the conveyor, when the belt deviates and comes into contact with the deviation switch vertical roller, the vertical roller rotates automatically. If the deviation continues to increase, the squeezing vertical roller will shift. When the deflection angle of the vertical roller exceeds 20 degrees; When the first level switch is activated, an alarm signal is output. When the deflection angle of the vertical roller exceeds 35 degrees; When the above occurs, the secondary switch acts and outputs a shutdown signal. The first level switch signal is used for alarm. If this signal is connected to the running adjustment device, it can achieve automatic adjustment of running deviation without stopping the machine. The second level switch signal is used for shutdown. Connect this signal to the control circuit to achieve automatic shutdown under severe deviation. After troubleshooting, when the tape leaves the vertical roller for normal operation, the vertical roller can automatically reset< br />    The protection level of the deviation switch is as high as IP67, which can prevent the entry of dust and water erosion. The inclination angle can reach up to 75 degrees;, Higher degrees of freedom. The dual bearing transmission structure adopted by this deviation switch avoids direct friction between the transmission shaft and the housing or shaft sleeve during switch operation, resulting in increased clearance, loose sealing or jamming, greatly extending the service life of the switch; The cam of the deviation switch is made of die cast aluminum, with a surface shot blasting treatment and independent action, making it easy to adjust the switch action angle according to actual needs; The surface of the shell is exquisitely baked with paint, which is not easy to peel off and has no odor, etc. This deviation switch has complete functions and the quality has reached the standard< br />  Prefabricated stainless steel junction box platinum resistor WZPK-125U,
