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, communication, scientific research, microwave energy utilization, and other fields. After the 1960s, 微波, 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. 因此, it has the advantages of fast heating speed, high heat utilization rate, and can achieve fast automatic control. 因此, it is widely used in industries such as medical treatment, chemical research, food processing, and material heat treatment. 然而, due to its ultra-high frequency electromagnetic wave, there is a strong electromagnetic field, and temperature measurement in the microwave field remains a technical challenge. 例如, in the temperature measurement problem of microwave reactors, under strong electromagnetic fields, when using conventional temperature sensors (如热电偶, thermistors, 等。) for temperature measurement, metal temperature probes and wires produce induced currents under high-frequency electromagnetic fields. 由于集肤效应和涡流效应, 他们自己的温度升高, 对温度测量造成严重干扰, 导致温度读数出现重大误差或温度测量不稳定. 因此, 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, chemical, seasoning, pharmaceuticals, biological products, wood, paper, ceramics, and tea making. 然而, 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.
