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, microwave, 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. Yog li ntawd, it has the advantages of fast heating speed, high heat utilization rate, and can achieve fast automatic control. Yog li ntawd, it is widely used in industries such as medical treatment, chemical research, food processing, and material heat treatment. Txawm li cas los, 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. Piv txwv li, in the temperature measurement problem of microwave reactors, under strong electromagnetic fields, when using conventional temperature sensors (xws li thermocouples, thermistors, lwm.) for temperature measurement, metal temperature probes and wires produce induced currents under high-frequency electromagnetic fields. Due to skin effect and eddy current effect, lawv tus kheej kub nce, causing serious interference to temperature measurement, resulting in significant errors in temperature readings or unstable temperature measurement. Yog li ntawd, 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. Txawm li cas los, 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.
