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, wissenschaftliche Forschung, microwave energy utilization, und andere Bereiche. After the 1960s, Mikrowelle, 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. Deshalb, it has the advantages of fast heating speed, high heat utilization rate, and can achieve fast automatic control. Deshalb, it is widely used in industries such as medical treatment, chemical research, food processing, and material heat treatment. Aber, 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. Zum Beispiel, in the temperature measurement problem of microwave reactors, under strong electromagnetic fields, when using conventional temperature sensors (wie z.B. Thermoelemente, thermistors, etc.) for temperature measurement, metal temperature probes and wires produce induced currents under high-frequency electromagnetic fields. Durch Hauteffekt und Wirbelstromeffekt, die eigene Temperatur steigt, was zu schwerwiegenden Beeinträchtigungen der Temperaturmessung führt, was zu erheblichen Fehlern bei den Temperaturmesswerten oder instabilen Temperaturmessungen führt. Deshalb, 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. Aber, 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, starkes elektromagnetisches Feld, und Umgebungen mit starken Interferenzen; Und eine genaue Temperaturmessung wurde durch die Sonde des fluoreszierenden Temperatursensors erreicht. 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.
