Abstract
PURPOSE: To execute detection with high accuracy, by installing a medium to be detected, having three reference surfaces meeting at right angle with each other, to an object to be detected, making plural contacts each contact with each reference surface of the object to be detected, and detecting and calculating the extent of displacement of each contact by a detecting means.
CONSTITUTION: A medium to be detected 2 has three reference surfaces 2X, 2Y and 2Z meeting at right angle with each other, and to each of these reference surfaces 2X, 2Y and 2Z, the tips of differential transformers 3W of suitable number (the figure shows an execution example of 4 pieces) are brought into abutment respectively. A supporting body 4 also has three plate surfaces 4X, 4Y and 4Z meeting at right angle with each other, is fixed through fixed members 17W in a vessel 1 stored in an atomic reactor, and consideration is taken so that the supporting body 4 itself causes no displacement due to thermal deformation or vibration. The medium to be detected 2 is installed to an object to be detected so that the reference surface 2X, the reference surface 2Y and the reference surface 2Z are parallel with the plate surface 4X, the plate surface 4Y and the plate surface 4Z, respectively.
