高温测量与连续控温在工程、生产过程和科研中是一个十分重要,而复杂的问题。由于外界的影响引起敏感元件材料不稳定,使接触式温度计量器具(如热电偶、电阻温度计等)的应用受到了限制。因此,在高温测量中经常采用不接触方法—光学高温计和辐射高温计。但是光学高温计的测量结果带有主观性,并且不能实现自动检测,而辐射高温计难于测量小
High temperature measurement and continuous temperature control in engineering, production processes and research is a very important and complex issue. The application of contact-type temperature measuring instruments (such as thermocouples, resistance thermometers, etc.) is limited due to the instability of the sensing element due to external influences. Therefore, non-contact methods are often used in high temperature measurements - optical pyrometers and radiation pyrometers. However, the measurement results of the optical pyrometer with subjectivity, and can not achieve automatic detection, and the radiation pyrometer is difficult to measure small
