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, تواصل, scientific research, microwave energy utilization, وغيرها من المجالات. After the 1960s, ميكروويف, 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. لذلك, it has the advantages of fast heating speed, high heat utilization rate, and can achieve fast automatic control. لذلك, it is widely used in industries such as medical treatment, chemical research, food processing, and material heat treatment. لكن, due to its ultra-high frequency electromagnetic wave, هناك مجال كهرومغناطيسي قوي, and temperature measurement in the microwave field remains a technical challenge. على سبيل المثال, in the temperature measurement problem of microwave reactors, under strong electromagnetic fields, when using conventional temperature sensors (مثل المزدوجات الحرارية, الثرمستورات, إلخ.) لقياس درجة الحرارة, 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, مما يسبب تدخلا خطيرا في قياس درجة الحرارة, resulting in significant errors in temperature readings or unstable temperature measurement. لذلك, 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, كيميائية, seasoning, pharmaceuticals, biological products, wood, paper, ceramics, and tea making. لكن, 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.

Microwave fluorescence fiber optic temperature measurement system

The microwave temperature measurement system using fluorescence fiber optic temperature measurement utilizes the characteristics of fiber optic fluorescence temperature measurement’s immunity to electromagnetic radiation fields to accurately measure the temperature of the object to be heated in the microwave cavity in ultra-high frequency, strong electromagnetic field, and heavy interference environments; And accurate temperature measurement was achieved through the probe of the fluorescent temperature sensor. Fiber optic temperature measurement systems are suitable for integrated single channel or multi-channel temperature measurement, and fluorescent fiber optic temperature measurement equipment is particularly suitable for high-frequency and microwave equipment.
