| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a displacement detector capable of transmitting the displacement of a gage head with higher accuracy in the measurement of an inner diameter of a tube.SOLUTION: A displacement detector detects a displacement of a distance between a first portion of a structure and a second portion of the structure facing the first portion. The displacement detector includes: a gage head 102 biased in a direction of the first portion to come into contact with the first portion and having a conductive part 102b; and an eddy current sensor 104 provided in a support part 101, biasing the gage head 102 to the direction of the first portion to support it and being in contact with the second portion, and detecting a displacement of a distance to the conductive part 102b of the gage head 102 displaced against biased power in the first portion.SELECTED DRAWING: Figure 1
【課題】 管体の内径の測定において、より高い精度で測定子の変位を伝達することができる変位検出装置を提供する。【解決手段】 構造物の第１部分と第１部分に対向する構造物の第２部分との距離の変位を検出する変位検出装置１であって、第１部分の方向へ付勢されて第１部分に当接され、導電部１０２ｂを有する測定子１０２と、測定子１０２を第１部分の方向へ付勢して支持するとともに第２部分に当接される支持部１０１に設けられ、第１部分により付勢力に抗して変位した測定子１０２の導電部１０２ｂとの距離の変位を検出する渦電流センサ１０４とを備えた。【選択図】図１ |
