산업용 고온 측정 분야, 전통적인 열전대 온도 측정이 널리 사용됩니다., but it has disadvantages such as poor corrosion resistance, 짧은 수명, high consumption, and high price. Radiation temperature measurement technology has attracted the attention of researchers since its inception due to its strong anti-interference ability, immunity to environmental influences, 그리고 빠른 응답속도. The traditional non-contact high-temperature radiation temperature measurement method usually exposes its optical collection system to high temperature environments. Prolonged exposure to high temperature environments can easily cause lens corrosion or vapor deposition, leading to deterioration of the optical collection system and resulting in measurement errors.

Sapphire tube blackbody cavity 광섬유 온도 측정 장치, including optical system and circuit system

The optical system includes a sapphire tube blackbody cavity, a lens group lens, and a Y-shaped transmission fiber. The circuit system includes a photodetector, a signal processing module, and a display module;

The sapphire tube blackbody cavity is formed by coating the inner side of the sealed end of the sapphire tube. The sapphire tube blackbody cavity serves as the sensing part and comes into contact with the environment to be measured, and converges the thermal radiation energy at the ambient temperature through a lens group to a Y-shaped energy transmission fiber. The Y-shaped energy transmission fiber divides the thermal radiation energy into two energy beams of different bands. The two branch ends of the Y-shaped energy transmission fiber are respectively connected to a photodetector. The photodetector converts the two energy beams into electrical signals and transmits them to the signal processing model for signal processing, obtaining a digital signal. The display module obtains the temperature value to be measured based on the digital signal and displays it. Can meet the temperature measurement range requirements of some explosion scenarios;
Sapphire has stable physical and chemical properties at high temperatures, excellent chemical corrosion resistance, and can work for long periods of time in explosive and high-temperature environments; The thermal capacity of the blackbody cavity in the sapphire fiber blackbody method is very small, and it can reach thermal equilibrium in a very short time when in contact with an explosive heat source. 그 다음에, the light signal radiated from the blackbody cavity is transmitted to the photodetector at the speed of light through the sapphire fiber.

This process takes a very short time, so the sapphire fiber blackbody temperature measurement system has a very fast response speed, meeting the dynamic response requirements of explosive flame temperature measurement. Sapphire fiber has good electrical insulation and resistance to electromagnetic interference, which can output explosion flame temperature signals with minimal loss

In industrial applications, high-temperature measurement technology is mainly divided into two types: contact and non-contact.

Common contact temperature measurement methods include platinum rhodium thermocouples, tungsten rhenium thermocouples, 등. They are all precious metals, 값비싼, and have poor oxidation resistance, reduction ability, 및 전자기 간섭 저항. They also have a short lifespan and cannot achieve the fusion and distributed measurement of temperature signals from multiple sensors.

The non-contact temperature measurement method allows the sensor to not come into contact with the object, but instead uses a lens to receive thermal radiation from the surface of the object. The non-contact temperature measurement method does not change the temperature distribution of the measured object, and has the advantages of fast thermal radiation speed and small thermal inertia of the detection element, thus achieving rapid measurement.

Sapphire fiber optic high-temperature sensors have advantages such as high melting point (2040 ℃), 작은 크기, high hardness, 내식성, 전자기 간섭에 대한 내성. They have performance advantages that cannot be compared to other temperature measurement methods in high-frequency heating furnaces, microwave heating furnaces, and other environments with strong electromagnetic interference. The infrared radiation type sapphire fiber high-temperature sensor uses optical fibers for sensing and transmitting optical signals, and uses colorimetric temperature measurement methods to determine the temperature of an object based on the ratio of its radiation energy density at adjacent wavelengths. In applications where the intermediate medium absorbs a large amount, such as environments with smoke, 먼지, 증기, and particles, as well as changes in the emissivity of the target surface, the attenuation of radiation energy is almost the same at two wavelengths, so it does not affect the ratio between them and can still achieve high accuracy.

Infrared radiation type sapphire fiber high-temperature sensor and temperature measurement system. Using colorimetric temperature measurement method, the ratio of spectral radiation energy of the measured object at two different specified wavelengths is measured through sapphire fiber, photodetector, and oscilloscope to achieve temperature measurement. Eliminating the influence of object emissivity on measurement results makes measurement more convenient and reliable.
