Description
Technical field
The invention belongs to the technical field of the temperature digital display instrument Site Detection of adapted thermopair, specifically, the present invention relates to a kind of termination of the temperature digital display instrument for detection of adapted thermoelectricity even number.
Background technology
In the Site Detection of the temperature digital display instrument of adapted thermopair, calibrate temperature digital display instrument by multi-function calibrator as standard, and standard and tested instrument all have reference junction temperature automatic compensation function, the millivolt value that two sides temperature difference compensates is also different, uses corresponding compensating wire to connect and just in time can offset this difference.
In the prior art, the front end of compensating wire is connected with multi-function calibrator by corresponding acting thermocouple plug, and the end of compensating wire is by artificial wiring and tested Instrument connection.Site Detection often quantity is many, surrounding environment complexity, one by one artificial wiring inefficiency.
Summary of the invention
Problem to be solved by this invention is to provide a kind of termination of the temperature digital display instrument for detection of adapted thermoelectricity even number, its objective is the reliability and the work efficiency that improve temperature digital display instrument Site Detection.
To achieve these goals, the technical scheme that the present invention takes is:
The termination of a kind of temperature digital display instrument for detection of adapted thermopair provided by the present invention, comprise multi-function calibrator, acting thermocouple plug, compensation lead of thermocouple, test pencil folder, insulating sleeve, tested instrument, the both positive and negative polarity of described compensation lead of thermocouple front end is connected with the both positive and negative polarity of acting thermocouple plug wiring pile crown respectively, the both positive and negative polarity of compensation lead of thermocouple end welds with the end of test pencil folder respectively, and described test pencil folder puts respectively the insulating sleeve of its outer rim of parcel.
According to thermopair middle conductor law: access the third metal material in For Thermocouple Circuit, as long as the temperature at these the third metal material two ends is identical, the thermoelectrical potential that thermopair produces remains unchanged, and is not subject to the impact of the third metal access.So the third metal being accessed by welding test pencil does not affect the thermoelectrical potential in loop, do not affect the displayed value of tested instrument.
For making the present invention more perfect, following more detailed and concrete technical scheme has also further been proposed, to obtain best practical function, realize better goal of the invention, and improve novelty of the present invention and creativeness:
The length of described insulating sleeve is equal to the length of test pencil folder.
