In the fields of modern industrial manufacturing, aerospace, and material heat treatment, the choice of high-temperature rotating body temperature measurement scheme is directly related to the safety of equipment operation and the yield rate of products. Traditional temperature measurement methods often struggle to balance the dual challenges of “high temperature” and “rotation” in extreme working conditions such as engine turbines, heat treatment furnace rollers, and rotary kilns. With the development of sensing technology, temperature sensors based on special materials and wireless transmission are breaking through this bottleneck, providing new ideas for status monitoring of dynamic thermal equipment.
In cutting-edge fields such as aviation engines, high-temperature rotating body temperature measurement solutions need to cope with harsh environments exceeding 1000 ℃. Researchers are using innovative structural designs, such as separating inductors and capacitors, and utilizing electromagnetic coupling technology to achieve signal transmission. This temperature sensor can monitor the temperature distribution of ceramic blades in real-time under high-speed rotation, and maintain signal stability and sensitivity even in ultra-high temperature environments of 1100 ℃, providing key data support for evaluating the service status of hot end components.
For different industrial application scenarios, high-temperature rotating body temperature measurement solutions present diversified technological paths. For example, a scanning infrared thermometer can measure the uniaxial temperature distribution of rapidly moving or rotating objects at a speed of up to 150Hz by scanning the optical axis through a rotating mirror, which is very suitable for online monitoring of heating steel plates or furnace shells. In the annealing of steel pipes or homogenization treatment of aluminum billets, a dedicated rotary high-temperature furnace tracking system uses a cylindrical insulation box to directly install the temperature sensor at the end of the product. It rotates synchronously with the workpiece in the furnace up to 1000 ℃, and truly records the penetration temperature of the workpiece throughout the heat treatment process to ensure temperature uniformity.
Whether using non-contact infrared measurement or high-temperature resistant contact probes, a comprehensive high-temperature rotating body temperature measurement solution not only relies on the hardware itself, but also requires strong signal processing capabilities. For example, temperature sensors using phosphor coatings or wireless radio frequency technology can operate stably in centrifugal fields, and transmit real-time data back to the analysis system through optical windows or antennas, effectively avoiding the drawbacks of traditional slip ring conductors being prone to wear and interference. This precise real-time temperature measurement capability plays an irreplaceable role in optimizing process parameters and preventing thermal damage to rotating components. In summary, in the face of increasingly stringent industrial temperature measurement requirements, only by combining innovative structural design, high-temperature resistant materials, and intelligent algorithms can a truly reliable high-temperature rotating body temperature measurement solution be constructed.
