Abstract
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
The present invention relates to sensor, particularly a kind of line-type temp sensor being mainly used on the equipment such as generator.
Background technology
Temperature sensor is to apply a kind of sensor quite widely, in a lot of fields, all plays an important role, and is particularly applied to the temperature sensor in electrical generator fields, has the effect of surveying generator-temperature detection, can prevent that fire from occurring.But existing temperature sensor is a temperature sensor for galvanic couple formula, can not survey to globality the temperature of generator, if certain some increase in temperature of generator, and by chance do not put the temperature sensor of galvanic couple formula herein, cannot survey so, affect whole generator-temperature detection detection accuracy, cause temperature sensing inaccurate, have disaster hidden-trouble.
Summary of the invention
Technical matters to be solved by this invention is: the line-type temp sensor that a kind of temperature sensing precision is high, reliability is high is provided.
The present invention solves technical scheme that its technical matters adopts: line-type temp sensor, comprise the first electrode layer and the second electrode lay, and the first electrode layer is tubular, at the outside surface of the first electrode layer, is provided with insulation course; The second electrode lay is positioned at the first electrode layer inside center and arranges along the axial line of the first electrode layer, between this first electrode layer and the second electrode lay, is filled with temperature semiconductor material.
Described temperature semiconductor material is semiconductor ceramics powder.
Described the first electrode layer and the second electrode lay are made by stainless steel material.
The invention has the beneficial effects as follows: line-type temp sensor of the present invention, during use, whole line-type temp sensor is wrapped on testee, it is insulation course laminating testee, when testee temperature raises, heat passes in line-type temp sensor, temperature semiconductor material temperature raises, resistance reduces, there is voltage change signal in the first electrode layer and the second electrode lay, detectable testee temperature variation, is installed on inflammable equipment surface, the function that has Refuge Fire Action, eliminates disaster hidden-trouble.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, the 1-the first electrode layer, 2-the second electrode lay, 3-insulation course, 4-temperature semiconductor material.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described, but protection scope of the present invention is not limited to the following stated.
As shown in Figure 1, line-type temp sensor of the present invention, comprises that the first electrode layer 1 and the second electrode lay 2, the first electrode layers 1 are tubular, at the outside surface of the first electrode layer 1, is provided with insulation course 3; The second electrode lay 2 is positioned at the first electrode layer 1 inside center and arranges along the axial line of the first electrode layer 1, between this first electrode layer 1 and the second electrode lay 2, is filled with temperature semiconductor material 4.Line-type temp sensor of the present invention, during use, whole line-type temp sensor is wrapped on testee, be insulation course 3 laminating testees, when testee temperature raises, heat passes in line-type temp sensor, temperature semiconductor material 4 temperature raise, resistance reduces, there is voltage change signal in the first electrode layer 1 and the second electrode lay 2 that are connected with temperature semiconductor material 4 contact, i.e. detectable testee temperature variation, and line-type temp sensor is installed on inflammable equipment surface, the function that has Refuge Fire Action, eliminates disaster hidden-trouble.
Temperature semiconductor material can be chosen sensistor, also can choose photodiode etc., but use in online temperature sensor, these material costs are too high, and damage in easy online temperature sensor winding process, therefore as a kind of preferred material, described temperature semiconductor material is semiconductor ceramics powder.
Electrode layer material can adopt aluminium, copper etc., but because aluminium easily bends, it is more difficult to recover, and easy fracture, copper is too expensive again, and therefore the cost performance of comprehensive various materials, is that described the first electrode layer 1 and the second electrode lay 2 made by stainless steel material as preferred a kind of mode.
