Microwave electromagnetic anti-interference fiber optic temperature measurement system-INNO

Introduction to Microwave Electromagnetic Fluorescence Fiber Temperature Measurement System

Microwave belongs to ultra-high frequency electromagnetic waves, which have strong electromagnetic fields. When using conventional temperature sensors (열전대와 같은, thermal resistors, 등.) 온도를 측정하기 위해, metal temperature probes and wires produce induced currents under the high-frequency electromagnetic field. 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. 그러므로, the fluorescence fiber temperature measurement system independently developed by Fuzhou INNO is a non-interference temperature sensor in the microwave field. The microwave fiber optic temperature measurement system utilizes the characteristics of fiber optic fluorescence temperature measurement, which is immune to electromagnetic radiation fields, to accurately measure the temperature of the object to be heated in the microwave cavity in ultra-high frequency, 강한 전자기장, and heavy interference environments; 그리고 형광온도센서의 프로브를 통해 정확한 온도측정이 이루어졌습니다..

Fluorescent fiber optic temperature measurement belongs to the contact type temperature measurement method. This device achieves temperature measurement based on the length of fluorescence afterglow lifetime. The fluorescent substance applied to the remote temperature measuring end will emit corresponding fluorescence energy when stimulated by specific wavelengths of light. After removing the excitation of specific wavelengths of light, the fluorescence afterglow begins to decay. The duration of fluorescence afterglow depends on the temperature of the fluorescent substance located on the temperature measuring probe, 즉, the temperature of the substance to be measured. The selection of specific wavelength light excitation is matched with the selected fluorescent substance, and the most effective excitation wavelength of different fluorescent substances is different. 선택할 때, it is important to focus on selecting the light wavelength that is most suitable for exciting fluorescent substances. The attenuation curve of fluorescent substances excited by light is usually in a single exponential form.
