In the field of industrial high-temperature measurement, traditional thermocouple temperature measurement is widely used, but it has disadvantages such as poor corrosion resistance, short lifespan, high consumption, and high price. Teknologi pengukuran suhu radiasi telah menarik perhatian para peneliti sejak awal karena kemampuan anti-interferensinya yang kuat, kekebalan terhadap pengaruh lingkungan, dan kecepatan respons yang cepat. Metode pengukuran suhu radiasi suhu tinggi non-kontak tradisional biasanya memaparkan sistem pengumpulan optiknya ke lingkungan bersuhu tinggi. Kontak yang terlalu lama dengan lingkungan bersuhu tinggi dapat dengan mudah menyebabkan korosi lensa atau pengendapan uap, menyebabkan kerusakan sistem pengumpulan optik dan mengakibatkan kesalahan pengukuran.

Rongga benda hitam tabung safir pengukuran suhu serat optik perangkat, termasuk sistem optik dan sistem sirkuit

Sistem optik mencakup rongga benda hitam tabung safir, lensa kelompok lensa, dan serat transmisi berbentuk Y. Sistem sirkuit mencakup fotodetektor, modul pemrosesan sinyal, dan modul tampilan;

Rongga benda hitam tabung safir dibentuk dengan melapisi sisi dalam ujung tabung safir yang tersegel. Rongga benda hitam tabung safir berfungsi sebagai bagian penginderaan dan bersentuhan dengan lingkungan yang akan diukur, dan menyatukan energi radiasi termal pada suhu sekitar melalui kelompok lensa ke serat transmisi energi berbentuk Y. Serat transmisi energi berbentuk Y membagi energi radiasi termal menjadi dua berkas energi dengan pita berbeda. Kedua ujung cabang serat transmisi energi berbentuk Y masing-masing dihubungkan ke fotodetektor. Fotodetektor mengubah dua berkas energi menjadi sinyal listrik dan mentransmisikannya ke model pemrosesan sinyal untuk pemrosesan sinyal, memperoleh sinyal digital. 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. Kemudian, 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, sehingga sistem pengukuran suhu benda hitam serat safir mempunyai kecepatan respon yang sangat cepat, memenuhi persyaratan respons dinamis pengukuran suhu nyala api eksplosif. Serat safir memiliki isolasi listrik yang baik dan ketahanan terhadap interferensi elektromagnetik, yang dapat menghasilkan sinyal suhu api ledakan dengan kerugian minimal

In industrial applications, teknologi pengukuran suhu tinggi terutama dibagi menjadi dua jenis: kontak dan non-kontak.

Metode pengukuran suhu kontak yang umum mencakup termokopel platinum rhodium, termokopel renium tungsten, dll.. Semuanya adalah logam mulia, mahal, dan memiliki ketahanan oksidasi yang buruk, kemampuan reduksi, and electromagnetic interference resistance. Mereka juga memiliki umur yang pendek dan tidak dapat mencapai pengukuran sinyal suhu yang fusi dan terdistribusi dari beberapa sensor.

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 ℃), ukuran kecil, high hardness, ketahanan terhadap korosi, dan ketahanan terhadap interferensi elektromagnetik. 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, debu, steam, 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, rasio energi radiasi spektral objek yang diukur pada dua panjang gelombang tertentu yang berbeda diukur melalui serat safir, fotodetektor, Dan osiloskop untuk mencapai pengukuran suhu. Menghilangkan pengaruh emisivitas objek terhadap hasil pengukuran membuat pengukuran lebih mudah dan andal.
