摘要： The invention relates to a process for the detection of malfunctions, in particular the detection of breakage of a wire in a wire sawing device. The process consists in applying an alternating signal to the layer of wires (4) of the sawing device and measuring the variations of voltage or current at the terminals of the layer of wires. In a modification, there are measured variations of voltage induced by the layer of wires forming a primary circuit in an antenna (9) forming the secondary circuit of a resonant system. The invention also has for its object the device for practicing the process of the invention.
