Senzor de temperatură cu fibră optică, aplicație, Caracteristici

Odată cu dezvoltarea continuă a tehnologiei de detectare, Cererea oamenilor pentru tehnologia senzorilor crește, de asemenea, pe zi ce trece. Fiber optic sensors that meet the conditions of high sensitivity, cost redus, Proces simplu de preparare, and good stability are rare. În procesul de detectare și detecție, sensibilitatea și stabilitatea sunt principalii factori tehnici de influență, în timp ce procesul de preparare și costul sunt factori importanți care influențează producția industrială. 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, such as intensity, lungime de undă, frequency, phase, polarization state, etc., becoming the modulated optical signal. It is then sent through the optical fiber to the optoelectronic device and demodulated to obtain the measured parameters.

In the existing technology, there are many methods for temperature detection, and the sensors used mainly include bimetallic temperature sensors, thermistor temperature sensors, and infrared temperature detection devices. These temperature sensors all have different drawbacks, such as bimetallic temperature sensors being sensitive to electromagnetic radiation and not suitable for electromagnetic scenarios; Thermistor temperature sensors require a current source to be loaded during use, which can generate self heating over time. Thermistor temperature sensors are highly sensitive to self heating, causing self heating errors; 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.

Senzori de temperatură cu fibră optică have a wider range of applications due to their advantages of anti electromagnetic radiation and passive detection. The existing senzori de temperatură cu fibră optică 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, strong corrosion resistance, easy manufacturing, cost redus, răspuns rapid, and high detection sensitivity.

The advantages of senzori de temperatură cu fibră optică

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

2. There are particularly high requirements for accuracy, sensitivity, lifespan, stability/reliability, etc;

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

4. Flammable, explozibil, and corrosive environments have special requirements for safety/corrosion resistance.

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

6. Places where energy supply is inconvenient during testing.
