Method for monitoring microtome cutting unit, involves detecting vibration of cutter of cutting unit by acoustic sensor without contact, where sensor generates frequency spectrum which is evaluated by signal processing unit

摘要

The method involves detecting the vibration of a cutter (3) of the cutting unit by an acoustic sensor (8) without contact. The sensor generates a frequency spectrum which is evaluated by a signal processing unit (9) or a data processing unit (11). An alarm signal to an alarm unit (13) or a correction signal to a controller unit (12) is given based on the evaluation, which changes the operational state of the cutting unit. An independent claim is included for a device for monitoring a microtome cutting unit.
