A heat leveller machine can create valuable economical losses in fault situations. By applying on-line monitoring of the vibration signatures, the machine can be followed continuously and the changes in the process and in condition of the machine can be detected immediately. The on-line monitoring consists of the on-line adjustment of drive parameters as well as quality control. Generally several kinds of different sensor types are applied into the system. On-line monitoring of rolling bearings usually includes vibration measurement sensors. A heat leveller operates at different speeds and loads and the direction of process can be reversed during run. The reliability of the results of the on-line monitoring can be increased by measuring simultaneously different parameters that influence on the vibration of the machine.
