PURPOSE:To measure the distortional distribution of a construction which is to be used at a high temperature by adhering many elements made of thin wires of a heat proof metallic to the construction and observing the change of resistance caused by the temperature and distortion of these elements. CONSTITUTION:Melted heat-proof insulator 2 is applied on the upper surfae of construction 1, many elements 3a-3d made of minute wires of heat-proof metallic material are arrayed on the insulator 2 and then melted heat-proof insultor 2 is applied again over the elements 3 to fix them. In addition, the elements 3 are adhered to a small testing chip and the change of resistance cuased by the change of temperature and repeated distortion should be observed to grasp the temperature distribution, distortional distribution and the number of repeated times of distortion from element 3 adhered to construction 1. Thus, the distribution of temperature and distortion of construction 1 can be measured quantitatively and the damage of construction 1 can be prevented by measuring the distortion. |
