辐射测温(非接触测温)是利用物体的辐射能与温度之间存在一定关系来进行温度测量的。它与接触式测温(如热电偶、热电阻等)相比,有其独特的优越性。例如:辐射能探测器不必与被测物体相接触,不会破坏被测物体的温度场;可以测量移动或转动物体的温度;测温上限不受限制等等。但应用辐射式测温仪表测温吋,常常受到各方面的干扰。干扰大致可分为光路中介质干扰,外来光干扰、被测物体发射率的干扰及环境温度对探测器的干扰等。这些干扰影响测量精度,严重时使测量无法进行。北京钢铁学院仪表教研室经过两年多的努力,研制成功了TWC—光纤高炉铁水连续测温 Radiation temperature measurement (non-contact temperature measurement) is the use of the object’s radiation energy and temperature have a certain relationship between the temperature measurement. Compared with the contact temperature measurement (such as thermocouple, thermal resistance, etc.), it has its unique advantages. For example: the radiation detector does not have to be in contact with the measured object, will not undermine the temperature field of the measured object; you can measure the temperature of moving or rotating objects; temperature limit is not limited and so on. However, the use of radiation temperature measuring instrument temperature, often by all aspects of interference. Interference can be broadly divided into medium interference in the optical path, external light interference, interference of the emissivity of the measured object and interference of the ambient temperature on the detector. These disturbances affect the measurement accuracy, making the measurement impossible in severe cases.
