Abstract
The invention relates to a device for monitoring a conveyor (), comprising: The device according to the invention is characterized in that the device is additionally equipped with at least one structure-borne noise sensor () that detects deviations from the reference frequency, whereby a process computer () that is connected with the structure-borne noise sensor evaluates the change in frequency, specifically with simultaneous balancing with the reports from the optoelectronic system (), so that even in a case where the optoelectronic system itself does not report a critical state, an acoustical and/or optical alarm and/or in particular, an automatic shut-down of the conveyor is brought about, in that the process computer responsible for the structure-borne noise sensor is also connected with an alarm () and/or the drive control ().
