Table.This instrument can be used to measure moving object, Small object and thermal capacity is small or the surface of rapid (transition) object of temperature change
Temperature, it can also be used to the Temperature Distribution of measurement temperature field.
The most frequently used philosophy of the non-contact type thermodetector table based on black body radiation, referred to as radiation temperature measurement instrument.Radiation
Thermometry includes brightness method (see leucoscope), radiation method (see radiant-energy thermometer) and colorimetric method (see two-color thermometer).Respectively
Class radiative thermometric method can only measure corresponding radiance temperature, radiation temperature or colour temperature.(whole spokes only are absorbed to black matrix
Penetrate the object of not reflected light) measured temperature is only true temperature.The true temperature of object such as to be determined, then it must carry out material
The amendment of slin emissivity.And material surface emissivity by virtue depends not only on temperature and wavelength, but also with surface state, film and
Microstructure etc. is relevant, therefore is difficult accurate measurement.Generally required in automated production using radiation thermometry measuring or

The influence of spurious radiation can improve the Net long wave radiation of measured surface and effective emission ratio.Pass through instrument using effective emission ratio
Observed temperature is corrected accordingly, finally can obtain the true temperature of measured surface.Additional reflector the most typical is
Hemispherical reflectivity mirror.The stray radiant energy of measured surface is reflected back into surface by half-sphere mirror and forms spurious radiation near ball center,
It is material surface emissivity by virtue so as to improve ε in effective emission ratio formula, ρ is the reflectivity of speculum.
As for gas and the actinometry of liquid medium true temperature, then insertion heat proof material pipe can be used to certain depth
To form the method for blackbody cavity.Effective emission ratio of the cylinder cavity after reaching thermal balance with medium is obtained by calculating.
Can is modified to surveyed bottom of chamber temperature (i.e. medium temperature) with this value and obtains medium in automatic measurement and control
True temperature.
