With the rapid development of the aerospace industry and commercial rockets, our attention has once again turned to the vast expanse of space. News of launches by multiple commercial rocket companies has attracted widespread attention. Behind these achievements lies an indispensable material technology—thermal-insulation ceramic materials.

• High-Temperature Protection: During rocket launch and atmospheric re-entry, the high temperatures generated by air friction and engine combustion impose an enormous thermal load on the rocket’s structural materials. Ceramic materials offer excellent high-temperature stability and oxidation resistance, effectively preventing rockets from melting or burning due to excessive temperatures.
• Lightweight: Compared with traditional metallic materials, ceramic materials have a lower density, helping reduce rocket weight and increase effective payload capacity.
• Thermal Shock Resistance: Ceramic materials offer excellent thermal shock resistance and are less prone to cracking or fracture even during rapid heating or cooling of rockets.
• Excellent Thermal Insulation: Ceramic materials have low thermal conductivity, effectively isolating heat transfer between the interior and exterior of the rocket and protecting onboard equipment and crew.

Over the past two decades, non-contact infrared thermometers have developed rapidly, with continuously improving performance, an expanding range of applications, and steadily growing market share. Compared with contact temperature measurement methods, infrared thermometers offer advantages such as fast response, non-contact measurement, safer operation, and long service life. They can be used in various vacuum and non-vacuum furnaces, where they measure target temperatures directly through observation ports aimed at materials or heaters inside the furnace.

Fluke Process Instruments has extensive expertise and industry experience in this field. Fluke infrared thermometers can directly and accurately detect the actual temperature of a target, providing effective guidance for increasing or decreasing heating power. With fast response and multiple signal output options, standardized digital or analog signals can be transmitted directly to a host computer to create a closed-loop temperature control system. This greatly reduces the workload of frontline operators while helping ensure consistent product quality.

Fluke Process Instruments delivers outstanding performance in measurement accuracy, measurement stability, measurement range, and environmental adaptability, making it a preferred solution for temperature measurement in ceramic applications. In addition, Fluke offers a comprehensive product portfolio to meet a wide variety of application requirements.
