The FMS measuring roller normally substitutes a regular idler roller station of the conveyor belt. The FMS measuring roller is selected according to the width and troughing angle of the conveyor belt. The center roller and the two beveled side disks are mechanically separated and allow for easy adjustment of the belt cross section according to your specific belt type or dimensions. Both measuring roller axis are supported by force measuring sensors. This direct measurement at the point of load transmission makes the measuring system insensitive to forces that act in direction of the moving belt. Additional components (guiding beams and connections to the frame, etc.) to isolate the force are not required and lead to an extremely slim design. With an installation height of only 180 mm (7.1 in.) or 240 mm (9.5 in.) the FMS measuring roller can be easily installed where space is limited, e.g. in mobile crushers or screening plants. The adjustable support of the measuring roller can be adapted to various frame dimensions and widths.
