NON-INDUCTIVE STRAIN SENSOR AND ITS MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a non-inductive strain sensor and its measuring method capable of measuring accurately the strain of a measuring object even in an environment wherein a noise is generated under a high magnetic field and an extra-high voltage. SOLUTION: In this non-inductive strain sensor and its measuring method, the strain measurement in the environment wherein the noise is generated under the high magnetic field and the extra-high voltage can be performed by a grid 2 comprising a one-turn coil subjected to patterning so as to be mutually overlapped on the front and back of an insulating substrate 1 in an approximately reverse U-shape.
