Claims (1)
検出する亀裂検出装置において、所定位置に対向
して複数の孔が設けられた一対の絶縁シート間に
、複数の電位計測用リード線がそれぞれ一端部が
前記孔部に露出するように挟みこまれてなるセン
サと、前記センサの電位計測用リード線の他端部
が接続された電位測定器とを具備したことを特徴
とする亀裂検出装置。 In a crack detection device that uses the potentiometric method to detect cracks that occur at uncertain positions, a plurality of potential measurement lead wires are placed at one end between a pair of insulating sheets that have a plurality of holes facing each other at predetermined positions. What is claimed is: 1. A crack detection device comprising: a sensor which is sandwiched so as to be exposed in the hole; and a potential measuring device to which the other end of a potential measuring lead wire of the sensor is connected.
