摘要

PROBLEM TO BE SOLVED: To provide means for improving accuracy of a strain gauge performance determination device for determining performance of a strain gauge which measures strain of a member under a high-temperature environment associated with power generation on the basis of capacitance of a capacitor including a first electrode and a second electrode facing the first electrode.SOLUTION: A strain gauge performance determination device includes: a position changing section 10 for changing a position of one of a first electrode 101B and a second electrode 102B in such a state that the first electrode 101B and the second electrode 102B face each other; a characteristic measurement section 14 for measuring electrical characteristics of a capacitor; and a determination section 15 for determining performance of a strain gauge 100 according to the position on the basis of the electrical characteristics obtained by the characteristic measurement section 14.SELECTED DRAWING: Figure 1
