Abstract
There is provided a device for measuring a temperature of a metal object itself without being affected by an ambient temperature. A first invention provides a device for measuring a temperature of a metal object using at least one strain gauge, wherein the at least one strain gauge is attached to the metal object and a linear expansion coefficient of the strain gauge is different from a linear expansion coefficient of the metal object. A second invention provides a device for measuring a temperature of a metal object using two strain gauges, wherein the two strain gauges are attached to the metal object, directions of grids of the two strain gauges coincide with each other, a Wheatstone bridge circuit is formed using the two strain gauges, a linear expansion coefficient of a first strain gauge of the two strain gauges is larger than the linear expansion coefficient of the metal object and the linear expansion coefficient of a second strain gauge of the two strain gauges is smaller than the linear expansion coefficient of the metal object.
