3 terminology and units of measurement

3.1 Terms 3.1.1 Emitter Size Effect size-of-sourceeffect (SSE) Pyrometer output varies with the size of the measured object phenomenon, known as the radiation source size effect. Function SSE (l, d1, d2) is a quantitative description of size effect of radiation pyrometer. It represents a measure of the distance l is determined, the analyte D1 to the diameter d2, the relative change in the pyrometer output signal of the photodetector. Function SSE (l, d1, d2) is a pyrometer own characteristics. 3.1.2 distance effect distanceeffect (DE) Pyrometer output with distance between the measured object and the pyrometer is changed phenomenon known distance effect. function DE (d, l0, l) is a quantitative description of the effect from the pyrometer. It means that for a pyrometer measuring head covering Determining target analyte diameter d, measured by the distance l0 to l, the pyrometer output signal of the photodetector The relative change. Function DE (d, l0, l) is a pyrometer own characteristics. 3.2 units of measurement Standard photoelectric pyrometer according to the 1990 International Temperature Scale (ITS-90) indexing. Temperature in degrees Celsius (℃) Or Kelvin (K).

4 Overview

Works 4.1 Standard Optical pyrometer (hereinafter referred to as the pyrometer) is a non-contact thermometer table. Such an object is determined pyrometer Wavelength spectral radiance and brightness temperature of the object is determined according to Planck's radiation law. Planck's blackbody radiation The law states that determine the relationship between the temperature T of the blackbody spectral radiance Lb (λ, T) with a wavelength λ,. Lb (λ, T) = c1πλ -5 Ex (pc2λ) T - êê úú1 -1 (1) ......
