Description
Technical field
The present invention relates to technical field of temperature measurement, and in particular to a kind of measure platform of superhigh temperature burner hearth standard temperature with
And assay method.
Background technology
In the fields such as Aero-Space, Ferrous Metallurgy, refractory material, composite ceramicses, high-speed cylinder burning chemical petroleum, temperature
Detection is significant for aspects such as process optimization, safety in production, material property raisings.
Temperature is to determine one of important parameter of state of matter, and temperature is to affect material property, material composition, production technology
Important parameter, directly affect the change of gas componant, pressure, accurate determination of the environment temperature, reaction temperature, exhaust temperature,
Can effectively analyze and determine reactive state, in modern test technology, the frequency of temperature survey and application is far above other
Technical parameter.
For Accurate Determining temperature information, it is necessary to required according to the difference of measurement object, select suitable measuring method.Temperature
The measuring method of degree has many, can be divided into by the difference of temperature-measurement principle and temperature-sensitive components and parts used：Expansion type, resistance-type, heat
The special semiconductor temperature sensor of electric-type and radiant type and comparison, fibre optic temperature sensor etc..By temperature element whether with
Testee is contacted, and can be divided into contact and contactless.The thermometry that different measurement objects has which different, has solid
The surface thermometer of body surface planar survey, the measuring method for having surface of moving object temperature also have gas and temperature of liquid measurement side
Method.
In order to ensure the unification and accurately of temperature value, it should set up a standard scale for weighing temperature, referred to as
For temperature scale.International temperature scale is generally configured with：First, as close possible to thermodynamic temperature.2nd, reproducibility is high, and various countries can be with very high
Accuracy reappear same temperature scale, it is ensured that the unification of temperature value.3rd, for reappearing the normal thermometer user of temperature scale
Just, stable performance.
1996, CCT（International temperature Advisory Board）Recognize that international temperature scale, for the needs of High performance fixed-point, receives
CCT and CCPR（International light and radiation Advisory Board）Joint suggestion, encourage national measurement institute to carry out more than 2300K, weight
Research of the renaturation in the High performance fixed-point of 100mK.On the one hand purpose in order to improve temperature scale, reduces the uncertainty of high temperature temperature scale；
On the other hand it is to need High performance fixed-point to compare the concordance of international temperature scale and thermodynamic scale.At present, the carbon of some metals
Eutectic and carbon peritectoid Co-C（1324 DEG C of nominal temperature）、Pt-C（1738℃）、Re-C（2474℃）And WC-C（2750℃）Deng by
Divide reasonable in warm area, phase-change characteristic is excellent and has preliminary Research foundation, is CCT-WG5（International temperature Advisory Board
Radiation temperature measurement working group）The recommended reference point new as temperature scale and by various countries' temperature measurement laboratory extensive concern.
ITS-90 reference instruments will have platinum resistance thermometer, and measurement range is：13.8033k～961.78 DEG C, the state of China
In family's standard, using double platinum rhodium thermocouple as normal thermometer, temperature-measuring range is：1600 DEG C, industrial double platinum rhodium thermocouple can be with
1730 DEG C are measured, up to the present, the accurate measurement of 1800 DEG C of temperatures above in the world still suffers from many difficulties.Contact is surveyed
Warm instrument is fairly simple, reliable, and certainty of measurement is higher；But because temperature element and measured medium need to carry out sufficient heat exchange,
And need the regular hour to can be only achieved thermal balance, so there is the delay phenomenon of thermometric, while limited by exotic material,
May not apply to very high temperature survey, most important is that thermocouple is easy to damage, short life, poor reliability.Connect using non-
Touch temperature instrumentation such as infrared measurement technique, is that, come measurement temperature, temperature element is not required to and tested Jie by heat radiation principle
Matter is contacted, and infrared thermometer temperature-measuring range is wide, is not limited by the thermometric upper limit, and infrared thermometer will not also destroy measured object
The temperature field of body, response speed is typically also than very fast；But the external worlds such as emissivity, measurement distance, flue dust and aqueous vapor by object
The impact of factor, its measurement error are larger.
Research and application starting of the developed countries to gas temperature measuring technology is relatively early, wherein, the U.S., Germany, day
The states such as sheet, Britain, Russia, Italy, Sweden in terms of gas temperature measuring have done substantial amounts of research work, and have obtained
Important breakthrough.Through development for many years, technical merit of the China in terms of gas temperature measuring is greatly improved, but with
International standard is compared, and still suffers from gap.Various methods were attempted in terms of gas temperature measuring both at home and abroad.Original adoption thermoelectricity
Even, due to being contact type measurement, thermocouple is particularly easy to damage, and short life, poor reliability.It is in the fifties in last century, infrared
Technology initially enters the wide variety of stage, and at present both at home and abroad, the development of non-contacting infrared e measurement technology is extremely rapid, non-
It is often ripe.But the technology does not break away from the impact of certainty of measurement all the time, demarcate also complex.Grew up later
CCD imaging techniques have self-scanning characteristic, with noise it is low, sensitivity is high, dynamic range is big, low in energy consumption, small volume, lightweight
And the advantages of life-span length, using relatively broad in the measurement and diagnosis of the temperature fields such as boiler, internal combustion engine.Acoustic thermometry energy
Under suitable for rugged environments such as many dirt, high temperature, low temperature, and more accurately temperature data can be measured, it is easy to temperature
Field carries out on-line real time monitoring control.But fact proved the gas temperatures such as thermocouple, infra-red radiation, ccd image and acoustic thermometry
E measurement technology, is affected larger by gaseous environment, it is impossible to meet the temperature survey of special occasions, does not reach the measurement of measurand
Require.
Absorption of the gas to light can explain with Beer-Lambert laws that frequency passes through length for the single-frequency laser beam of ν
