摘要:
A compact monitoring device (6) for monitoring the state of rotation of a disk cutter (5) of a shield tunnel boring machine is integrated into a clamping element (15) for fastening the disk cutter (5). A sensor module (33) of the monitoring device (6) is arranged in close proximity to the disk cutter (5) but without touching so that a state of rotation of the disk cutter (5) generated by transmitters (34) mounted in the disk cutter (5) is reliably ensured even under the rough environmental conditions prevailing in shield tunnel boring.
