PURPOSE:To enable a shape returning critical temperature to match an object surface temperature by placing a shape-memory part of a thermal sensor body closest to a connection part with an object to be detected. CONSTITUTION:A shape-memory part 5 is set closest to a center of a connection part 4 with a stainless tie lap 2 (distance 1), a length m to both free edges of the sensor body 1 is reduced as much as possible, and a marking plate 6 is mounted to both free edges. Then, when an object to be detected results in an abnormal heat build-up, the marking plate 6 also stands up along with shape recovery of the sensor body 1 and the state can be easily confirmed also from a remote area, thus enabling a setting critical temperature of the sensor body 1 to match a surface temperature of a connection part when the shape recovers actually fully accurately and a highly accurate judgment to be made. |
