PURPOSE:To provide a sensor which performs a detection of a position where abnormal temperature is created, by a method wherein a pressure is applied to a pressurizing conductor through utilization of bending powers of ribbon-shaped bimetals to change the electric resistance. CONSTITUTION:Ribbon-shaped bimetals 1 and 2 are positioned facing and opposite to each other so that they bend in a reverse direction to each other, and a pressurizing conductor 5, producing a better conductor resulting from the application of a pressure between the bimetals, is inserted between 2 parallel wires 3 and 4. At a normal temperature (a), the bimetals 1 and 2 do not bend, whereby the pressurizing conductor 5 is not pressurized, it is reduced in an electric resistance, a short-circuiting occurs between the wires, and this permits the detection of a normal temperature part. |
