DEVICE AND METHOD FOR DETECTING METALLIC CONDUCTOR DISTURBANCE Russian patent published in 2017 - IPC G08B13/12 

FIELD: electricity.

SUBSTANCE: method for detecting disturbance in the metal conductor (34) comprises the stages of receiving the inductance sensor circuit (12) mechanically and electrically connected with the metallic conductor (34) with the monitored inductance value, the inductance sensor circuit (12) setting based on electromagnetic field applied externally to the metallic conductor (34), and on the internally generated circuit oscillation, and outputting the alarm in case of settings loss of the configured output signal from the configured inductance sensor circuit (12), caused by the change of the inductance value of the metal wire (34) while adding or removing at least a portion of the metallic conductor (34). The device (10) for detecting the metallic conductor disturbance according to said method is proposed as well. The device (10) comprises the inductance sensor circuit (12) made with the possibility of configuring the amplitude and/or frequency, and the alarm signalization circuit (16) for outputting an alarm signal based on the output signal of the inductance sensor circuit (12).

EFFECT: increasing the sensors sensitivity.
