Sensor suhu serat optik, aplikasi, karakteristik-INNO

Dengan terus berkembangnya teknologi penginderaan, permintaan masyarakat terhadap teknologi sensor juga semakin hari semakin meningkat. Sensor serat optik yang memenuhi kondisi sensitivitas tinggi, biaya rendah, proses persiapan sederhana, dan stabilitas yang baik jarang terjadi. Dalam proses penginderaan dan deteksi, sensitivitas dan stabilitas adalah faktor teknis utama yang mempengaruhi, sedangkan proses persiapan dan biaya merupakan faktor penting yang mempengaruhi produksi industri. Sensors that combine these advantages are receiving increasing attention and favor.

Fiber optic sensors are sensors that convert the state of the object being measured into measurable optical signals. The application range of fiber optic sensors is very wide, involving almost all important fields of national economy and defense, as well as people’s daily lives, especially for safe and effective use in harsh environments. The working principle of fiber optic sensors is to send the incident light beam from the light source into the modulator through an optical fiber. The interaction between the modulator and the external measured parameters changes the optical properties of the light, seperti intensitas, panjang gelombang, frekuensi, fase, keadaan polarisasi, dll., becoming the modulated optical signal. Kemudian dikirim melalui serat optik ke perangkat optoelektronik dan didemodulasi untuk mendapatkan parameter yang diukur.

Dalam teknologi yang ada, ada banyak metode untuk mendeteksi suhu, dan sensor yang digunakan terutama mencakup sensor suhu bimetalik, sensor suhu termistor, dan alat pendeteksi suhu inframerah. Semua sensor suhu ini memiliki kekurangan yang berbeda, seperti sensor suhu bimetalik yang sensitif terhadap radiasi elektromagnetik dan tidak cocok untuk skenario elektromagnetik; Sensor suhu termistor memerlukan sumber arus untuk dimuat saat digunakan, yang dapat menghasilkan pemanasan sendiri seiring waktu. Sensor suhu termistor sangat sensitif terhadap pemanasan sendiri, menyebabkan kesalahan pemanasan sendiri; Infrared temperature detection devices should be vertically incident on the surface of the object being detected during temperature measurement, which is inconvenient to use in narrow spaces.

Sensor suhu serat optik have a wider range of applications due to their advantages of anti electromagnetic radiation and passive detection. The existing sensor suhu serat optik can be pre embedded in narrow spaces to achieve temperature measurement. For objects without temperature measuring optical fibers, when temperature measurement is required, the optical fiber temperature sensor can also be pushed into the object through a traction device;

Accurate temperature measurement is crucial in engineering application systems such as aerospace, high-power stable lasers, and high-precision CNC machine tools. Fiber optic temperature sensors are mainly used to detect changes in external environmental temperature. Compared with ordinary electrical sensors, fiber optic sensors have no electromagnetic interference, ketahanan korosi yang kuat, easy manufacturing, biaya rendah, respon cepat, and high detection sensitivity.

Keuntungan dari sensor suhu serat optik

1. Traditional temperature sensors cannot function properly in electromagnetic/radio frequency environments due to severe interference;

2. There are particularly high requirements for accuracy, kepekaan, jangka hidup, stabilitas/keandalan, dll.;

3. The installation environment is narrow and there are special requirements for the sensor size;

4. Mudah terbakar, eksplosif, dan lingkungan korosif memiliki persyaratan khusus untuk keselamatan/ketahanan korosi.

5. In harsh environments such as lightning strikes and wilderness.

6. Places where energy supply is inconvenient during testing.
