It is occasionally the temperature element commonly used in temperature measuring instrument, its direct measurement temperature, and temperature signal is converted into thermo-electromotive force letter
Number, by electric meter（Secondary meter）It is converted into the temperature of measured medium.The normal pole because of needs of the profile of various thermocouples is not
It is identical, but their basic structure is roughly the same, generally by major parts such as thermode, insulation sleeve protection pipe and terminal boxes
Composition, generally supports the use with display instrument, recording apparatus and electronic controller.
The operation principle of thermocouple is by two kinds of conductors of different components（Referred to as thermocouple wire or thermode）Two ends engage
Into loop, when two temperature at abutment are different, electromotive force will be produced in the loop, this phenomenon is referred to as pyroelectric effect,
And this electromotive force is referred to as thermoelectrical potential.Thermocouple carries out temperature survey using this principle, wherein, it is directly used as measurement
One end of medium temperature is called working end（Also referred to as measurement end）, the other end is called cold end（Also referred to as compensating end）；Cold end with it is aobvious
Show instrument or matching instrument connection, display instrument would indicate that the thermoelectrical potential produced by thermocouple.
Theoretically, any two different conductor（Or semiconductor）Thermocouple is may be formulated into, but as practical
Temperature element, the requirement to it is many.In order to ensure the reliability in engineering technology, and enough measurement essences
Degree, not all material can constitute thermocouple, and typically to the electrode material of thermocouple, basic demand is：
1st, in temperature-measuring range, thermoelectric property stabilization, time to time change, does not have enough physical and chemical stabilities, no
Oxidizable or corrosion；
2nd, temperature-coefficient of electrical resistance is small, and conductance is high, and specific heat is small；
3rd, produce thermoelectrical potential big in thermometric, and it is linear between thermoelectrical potential and temperature or close to linear monotropic function
Relation；
4th, material replicability is good, high mechanical strength, and manufacturing process is simple, cheap.
【Utility model content】
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of anticorrosive property is strong, conductive
The structure of the New-type thermocouple that rate is high, specific heat is small.
A kind of structure of New-type thermocouple described in the utility model, including thermocouple body, thermocouple wire, its feature exist
In：Described thermocouple body is formed by ceramic material, and two through holes, described thermoelectricity are provided with described thermocouple body
The thermometric end of even body is provided with thermometric cap, and two described thermocouple wires connect through the through hole on thermocouple body with thermometric cap inner face
Connect；
To reach more practical function, further, described thermometric cap is made of Aludirome material；
Described thermocouple body one end is provided with mounting ring bulge loop；

【Specific embodiment】
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but it is not intended as to restriction of the present utility model.
As shown in Figure 1-2, a kind of structure of New-type thermocouple described in this specific embodiment, including thermocouple body, thermoelectricity
Thermo wires, its thermocouple body is formed by ceramic material, and its intensity is high, and chemical stability is strong, is unlikely to deform, and effectively protects thermoelectricity
Thermo wires, while the heat-resisting quantity of ceramics is stronger, its thermocouple body one end is provided with mounting ring bulge loop, using more square when installing
Just, for relatively conventional direct use electric wire lapping, it is unlikely to deform, prevents the displacement for installing the later stage from influenceing thermometric accurate
Degree, is provided with two through holes in the thermocouple body described in thermocouple body, two thermocouple wires through the through hole on thermocouple body with
Thermometric cap inner face is connected, and through hole effectively separates thermocouple wire, improves thermocouple wire security, and thermocouple body one end is provided with
Mounting ring bulge loop, the setting of mounting ring can facilitate the fixation in its installation process, more practicality, the thermometric end of its thermocouple body
Thermometric cap is provided with, thermometric cap is made of Aludirome material, and Aludirome material has excellent high-temperature oxidation resistant
Performance and relatively low temperature-coefficient of electrical resistance, effectively prevent the corrosion phenomenon during use, and its service life is more permanent, thermometric
Effect and accuracy are also greatly improved, on thermometric cap thermometric face for plane, its plane thermometric cap with by thermometric object
More fitted during contact, prevent the phenomenon of loose contact, also substantially increase the thermometric degree of accuracy of thermocouple.
The above is only better embodiment of the present utility model, therefore all according to described in the utility model patent claim
Construction, the equivalent change or modification done of feature and principle, be included in the utility model patent claim.
