However, the existing temperature sensor is a point galvanic temperature sensor, which cannot detect the temperature of the generator as a whole. If the temperature of a certain point of the generator increases, and there is no point galvanic temperature sensor, it will not be possible to detection, which affects the temperature detection accuracy of the entire generator, resulting in inaccurate temperature detection and fire hazards

The invention discloses a line-type temperature sensor which solves the problem that a point-type temperature sensor is low in precision and unreliable in temperature detection. The line-type temperature sensor comprises a first electrode layer and a second electrode layer. The first electrode layer is in a cylinder shape. An insulation layer is arranged on the outer surface of the first electrode layer. The second electrode layer is located in the center inside the first electrode layer and arranged along the axis line of the first electrode layer. Temperature semiconductor materials are filled between the first electrode layer and the second electrode layer. When the line-type temperature sensor is used, the whole line-type temperature sensor is wound on a detected object, namely, the insulation layer is attached to the detected object, when the temperature of the detected object rises, heat is transmitted into the line-type temperature sensor, the temperature of the temperature semiconductor materials rises, the resistance is reduced, voltage changing signals occur in the first electrode layer and the second electrode layer, and changes of the temperature of the detected object can be detected. The line-type temperature sensor is installed on the surface of an inflammable device and has the fire alarm and prompting functions, and fire hazards are eliminated.
Description
technical field [0001] The invention relates to a sensor, in particular to a linear temperature sensor mainly used in generators and other equipment. Background technique [0002] The temperature sensor is a widely used sensor that plays an important role in many fields, especially the temperature sensor used in the field of generators, which can detect the temperature of the generator and prevent fires. However, the existing temperature sensor is a point galvanic temperature sensor, which cannot detect the temperature of the generator as a whole. If the temperature of a certain point of the generator increases, and there is no point galvanic temperature sensor, it will not be possible to Detection will affect the temperature detection accuracy of the entire generator, resulting in inaccurate temperature detection and fire hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a linear temperature sensor with ...
