Description
When selecting a measuring wheel the kind of material to be measured has to be taken into consideration prior to any decision on wheel surface respectively cover lining. The wheel circumference depends on the space available as well as on the size of counter or encoder. The smaller the measuring wheel, the more force required at the wheel circumference and consequently the higher the risk of slip- page and incorrect measuring results. Also the width of the measuring wheel has an impact on the result.
