Abstract

A compact monitoring device for monitoring the state of rotation of a disk cutter of a shield tunnel boring machine is integrated into a clamping element for fastening the disk cutter. A sensor module of the monitoring device is arranged in close proximity to the disk cutter but without touching so that a state of rotation of the disk cutter generated by transmitters mounted in the disk cutter is reliably ensured even under the rough environmental conditions prevailing in shield tunnel boring.
