[0002] Industrial kilns are equipment made of refractory materials for calcining materials or firing products. They are divided into ceramic kilns and cement kilns. Their operating temperatures can reach 2500℃, and they require a large amount of fuel to maintain furnace combustion. Therefore, strict operating procedures must be formulated for management. Allowing kilns to burn at will will not only cause great waste, but also pose safety hazards, thus causing irreparable losses. Therefore, temperature measurement is required to monitor the combustion of each component in the kiln, which is usually achieved by infrared temperature measuring equipment. However, traditional infrared temperature measuring equipment has a relatively fixed angle during monitoring and cannot be adjusted in real time according to monitoring needs. There are problems such as detection blind spots. A new type of temperature measuring device is needed to solve the above problems. Utility Model Content
