一、概述辐射温度计测温属于非接触式测温,它可以测量远距离、高速运动、带电目标的温度。它具有反映速度快、灵敏度和分辨率高、测温范围宽等特点,因此得到广泛应用。但因各种原因,它也存在测量误差。本文将分析辐射温度计产生测量误差的原因及减少其误差的方法。二、辐射温度计测温的基本原理辐射温度计测温的基本依据是普朗克定律。普朗克从理论上给出了黑体辐射通量密度W_0(λ·T)与波长λ、绝对温度T的关系:
First, an overview of the radiation thermometer Temperature is non-contact temperature measurement, it can measure long-distance, high-speed movement, charging the target temperature. It has the characteristics of fast response, high sensitivity and resolution, wide temperature range and so on, so it has been widely used. But for various reasons, it also has measurement error. This article will analyze the causes of the measurement error caused by the radiation thermometer and the method to reduce the error. Second, the basic principles of radiation thermometer temperature measurement Radiation thermometer temperature is based on Planck’s law. Planck theoretically gives the relationship between the blackbody radiation flux density W_0 (λ · T) and the wavelength λ and the absolute temperature T:
