辐射类型的温度计依其工作波段可分成三种大的类型:全辐射温度计、部分辐射温度计和比色温度计。它们都是基于普朗克辐射公式或由它导出的维恩公式、瑞利一金斯公式、斯武藩一玻尔茨曼公式和维恩位移定律、物体辐射特性与温度的关系、物体的反射本领和吸收本领关系来测量物体表面温度的。全辐射温度计是利用测量(0、的)整个波长范围的辐射功率一卡测物体温度的;部分辐射温度计是利用测量某一波段上的辐射功率来测量物体温度的;比色温度计是利用测量两个或几个波段上的辐射功率比值或进行其他运算来测量物体温度的。由于它们的工作原理不同.因而呈现出不同的特性。在现场应用方面,它们受被测物体的人面黑度系数的影响、辐射传递通路中的介质吸收的影响也是不同的。在仪表的设计方面、对探测器的要求和对电路的要求也都不同。
Radiation type thermometers according to their working band can be divided into three major types: full radiation thermometer, partial radiation thermometer and colorimetric thermometer. They are all based on the Planck’s radiation formula or the derived Wien formula, the Rayleigh-Guinness formula, the Sivan-Boltzmann formula, and the Wien shift law, the relationship between the object’s radiation characteristics and temperature, the object’s Reflect the ability to absorb the ability to measure the surface temperature of the object. Full radiation thermometer is the use of measurement (0) of the entire wavelength range of the radiation power of a card test object temperature; part of the radiation thermometer is the use of measurement of radiation power on a band to measure the temperature of the object; colorimetric thermometer is the use of measurement of two Or several bands of radiation power ratio or other calculations to measure the temperature of the object. Because of their different working principles, they show different characteristics. In the field of application, they are affected by the surface blackness coefficient of the measured object, and the influence of medium absorption in the radiation transmission path is also different. In the design of the instrument, the detector requirements and the requirements of the circuit are also different.
