Project Description
Length measuring wheel
OK-III 200
Length measuring wheel OK-III 200 is device for measuring of lengths of square or band materials (i.e. for example length of (un)winding materials like textile, paper, non-woven…).
In this wheel with 200 mm perimeter, there are two ball-bearings. By default the axis of wheel is fastened to the steel swivelling arm 160 mm long. There is the electronic evaluating part in the measuring wheel which generates pulses while rotating. Due to these pulses it can be length and direction of rotating evaluated.
For evaluating of the pulses from measuring wheel we produce the universal electronic counter LUCA-T. See the details in the LUCA-T product description and operating manual.
