CKF.125...SHAFT THROUGH LOAD CELLS

A reliable web tension control may reduce web tears in order to increase productivity. CK load cells , used in a precise tension control system, are designed to carry out these delicate tasks.

They are installed in shaft through applications at the end of a measuring roller to precisely detect the resultant of the forces generated by pulling of the material depending on the wrapping angle.

CK shaft through load cells have been designed with a compact design, to easily t them in narrow spaces, to be installed very easily and to reach a very high reliability.Depending on models CK load cells are made with single or double foil.

CKF.125 load cells have a double xing possibility with 3 or 4 xing holes in order to be installed in all kind of applications.

Operating principle: CK load cells use the strain gauge operating principle to guarantee a perfect detection of the web tension. Strain gauges resistors are mounted on a inner metal foil of a load cell and connected to each other in a wheatstone bridge able to convert a mechanical movement into an electrical signal, that must be amplied by suitable ampliers.
