Fluorescent fiber optic thermometer is a fluorescence fiber optic temperature measurement system developed by FJINNO with years of technical strength. The fluorescence temperature measurement technology used has advantages that electric sensing technology cannot match, such as high temperature resistance, electromagnetic interference resistance, high-voltage insulation, ti gwosè, sansiblite wo, and long service life. It has received widespread attention and research. Sèjou, it has gradually entered the stage of commercial application and is applied in industries such as high-voltage electrical equipment, microwave industry, thermal therapy equipment, petrochemical industry, ayewospasyal, elatriye.

Fluorescent fiber optic temperature sensing technology has been applied in many fields due to its high reliability, bon pèfòmans izolasyon, entèferans kont elektwomayetik, good repeatability, fast response speed, ti gwosè, and low cost. As the core component of fluorescence temperature sensors, temperature probes are crucial for fiber optic sensors.

1. Good insulation.

This is the unique performance of optical fibers. Due to the transmission of optical signals in optical fibers, they are not easily disturbed even when used in harsh environments such as high voltage, high current, strong magnetic fields, and strong vehicle radiation. Epi tou, it is also beneficial to overcome the influence of medium atmosphere and background radiation in the optical path, making it suitable for temperature measurement in some special situations. Because it does not generate sparks, it will not cause explosions or combustion, is safe and reliable, and can solve problems that other thermometers cannot solve.

2. Quick response

Even in the case of a small object being tested, the optical path can still accept radiation energy from a larger solid angle, resulting in high measurement sensitivity. Due to the low transmission loss of quartz optical fiber, it can achieve the purpose of measuring long-distance transmission at close range with small lunar markers, meeting various on-site usage requirements.

3. The structure of fiber optic sensors is simple, with a small volume, the lightest weight, low power consumption, and no damage to the measured temperature field;

4. High strength, resistant to high temperature and pressure, resistant to chemical corrosion, and stable physical and chemical properties.

5. Fiber optic is flexible and flexible, overcoming the disadvantage of the optical path not being able to turn. It can be used for temperature measurement in special environments such as enclosed and narrow spaces.

6. The fiber optic configuration is flexible and can be made into single, bundle, Y-shaped, array and other structural forms, which can achieve temperature measurement in situations where general overflow meters are difficult to apply.

Classification of fiber optic thermometers

The main feature of fiber optic thermometers is that they have a temperature measuring probe with fiber optic, and the length of the fiber optic varies from a few meters to several hundred meters, collectively referred to as fiber optic temperature sensors. According to the role of optical fibers in sensors, they are divided into two categories: functional (FF) and non functional (NFF).

(1) Functional fiber optic thermometer. Also known as all fiber type or sensor type fiber optic thermometer. Its characteristic is that the optical fiber serves as both a temperature sensing element and a light guide. This type of fiber optic thermometer has excellent performance and a complex structure, which poses certain difficulties in production.

(2) Non functional fiber optic thermometer. Also known as a transmission type fiber optic thermometer. Its characteristic is that the temperature sensing function is completed by non fiber optic sensitive components, and the fiber optic only plays a guiding role. This fiber optic thermometer has stable performance, simple structure, and is easy to implement. Koumanse, most practical fiber optic thermometers are of this type, and the optical fibers used are mostly multimode quartz fibers.

According to different usage methods, fiber optic thermometers can be further divided into:

(1) Contact type fiber optic thermometer. Use a fiber optic temperature sensor to make contact with the object being measured. Such as fluorescent fiber optic thermometers, semiconductor absorption fiber optic thermometers, elatriye.

(2) Non contact fiber optic thermometer. The use of optical fiber temperature sensors does not come into contact with the object being measured, but uses the principle of thermal radiation to sense temperature. The optical fiber receives and transmits the thermal radiation on the surface of the object being measured, so it is also called an optical fiber radiation thermometer.
