Product Description
This machine is used on belt conveyors to prevent serious accidents caused by slippage. lt can also be used for chain startingand stopping of multiple belt conveyors, low speed holding or over speed protection, etc., making the operation on site simpleand improving safety. lt is widely used in industries with belt conveyors such as steel, electric power, coal mines and ports.
Working principle:
This product is used within the working vollage range of AC220V +10%, 50Hz, the speed range is 20-999R/MIN, output state:NC type. When out of the wheel (from the disk) with the tape machine running and drive the inner pulse disk, in the pulse diskrotalion sensor maqnelic should signal input to the control circuit, by trigger amplificalion output, and then count, its count value and preset number comparison, to judge the tape belt speed, namely: normal speed, skidding speed, overspeed speed, etc.. At the same time, the corresponding switch signal is output from the execution circuit to achieve the monitoring purpose.
