Fluorescent fiber optic temperature sensors used for temperature measurement in microwave environments-INNO

Fiber optic sensor for microwave temperature measurement

Microwave refers to electromagnetic radiation in the frequency range of 300MHz to 300GHz in the electromagnetic spectrum, characterized by high frequency, short wavelength, and the ability to penetrate the ionosphere. It can be applied in radar, comunicación, investigación científica, microwave energy utilization, y otros campos. After the 1960s, microonda, as a new type of heat source, developed rapidly. Its heating characteristics include on-site heating, simultaneous heating inside and outside, and instant high temperature without the need for heat transfer. Por lo tanto, it has the advantages of fast heating speed, high heat utilization rate, and can achieve fast automatic control. Por lo tanto, it is widely used in industries such as medical treatment, chemical research, procesamiento de alimentos, and material heat treatment. Sin embargo, due to its ultra-high frequency electromagnetic wave, hay un fuerte campo electromagnético, and temperature measurement in the microwave field remains a technical challenge. Por ejemplo, in the temperature measurement problem of microwave reactors, under strong electromagnetic fields, when using conventional temperature sensors (como termopares, termistores, etc.) para medición de temperatura, metal temperature probes and wires produce induced currents under high-frequency electromagnetic fields. Due to skin effect and eddy current effect, their own temperature rises, causing serious interference to temperature measurement, resulting in significant errors in temperature readings or unstable temperature measurement. Por lo tanto, the study of non-interference temperature sensors for microwave fields has significant practical significance.

Industrial microwave ovens are mainly used for drying and sterilization in industries such as food, químico, seasoning, pharmaceuticals, biological products, wood, papel, ceramics, and tea making. Sin embargo, due to the generation of a large amount of microwave radiation during the operation of microwave components, non-metallic items are exposed to high interference environments, making it impossible to effectively detect the temperature in the working area of microwave components, which brings inconvenience to the automatic control and safety of microwave components during use.
