Problems solved by technology

[0002] With the development of science and technology, the traditional contact temperature measurement method can no longer meet the temperature measurement needs in some modern fields, and the demand for non-contact and long-distance temperature measurement technology is increasing, so infrared temperature measurement sensors are widely used today And many fields, but the infrared temperature sensor has high requirements on the application environment, so the infrared temperature sensor has the problem of inaccurate data collection in the high temperature and dusty air preheater, and it is prone to damage and inconvenient maintenance.
