Get PriceThe third way to monitor conveyor speed is to attach an encoder to an encoder measuring wheel that rides on the surface of the belt or one of the rollers if the belt itself is crowded with product Typically these wheels are 1 foot in circumference which makes an easy conversion from RPM to linear speed
Get PriceThe first way to resolve your belt speed issue is to acquire the belt speed accurate prior to addressing any of your load sensor accuracy issue s There are many types of speed sensors used on conveyor belt scales The speed sensor is commonly coupled to the shaft of a non drive pulley in contact with the conveyor belt at all times
Get PriceIf you need more accurate then you need a feedback device on the conveyor which also needs its output scaled to the actual conveyor speed Spend all day calculating these numbers and then you will find out that the motor does not go 1725 RPMs at 60Hz and the gear reduction is not nominal and the belt on the conveyor slips etc etc etc
Get PriceTo calculate the speed of conveyor belts we must know the circumference of drive roller and revolutions per minute The product of the perimeter of the roller and revolutions per minute gives us the speed of the conveyor belts If suppose we have
