What are the advantages of fiber optic sensors compared to conventional sensors-INNO

Sensorer za optic za nyuzi are no stranger to people’s lives nowadays, as they can be applied in many aspects of people’s lives, such as temperature and humidity measurement, kipimo cha shinikizo, vibration measurement, nk. Traditional sensor technology may not be able to adapt to so many measurement needs.

(1) Unyeti wa juu. The response speed of fiber optic sensors is very fast, and the various physical values that can be measured are also very small.

(2) Kuingilia kati kwa sumakuumeme, insulation ya umeme, upinzani wa kutu, na usalama wa ndani.

Due to the fact that fiber optic sensors use light waves to transmit information, and fiber optic is an electrically insulated, corrosion-resistant transmission medium that is safe and reliable, it can be conveniently and effectively used in various large electromechanical, petrochemical, mining and other harsh environments with strong electromagnetic interference and flammable and explosive properties.

(3) Kasi ya kipimo cha haraka. Light has the fastest propagation speed and can transmit two-dimensional information, making it suitable for high-speed measurements. The analysis of radar and other signals requires a very high detection rate, which is difficult to achieve using electronic methods. High speed spectral analysis using the diffraction phenomenon of light can solve this problem.

(4) Large information capacity. The measured signal is carried by light waves, and the frequency of light is extremely high, which can accommodate a wide frequency band. The same optical fiber can transmit multiple signals.

(5) Suitable for harsh environments. Fiber optic is a dielectric material that is resistant to high voltage, kutu, na kuingiliwa kwa sumakuumeme. It can be used in harsh environments that other sensors are not suitable for.

Aidha, fiber optic sensors also have the characteristics of light weight, ukubwa mdogo, kubadilika, wide range of measurement objects, good reusability, na gharama ya chini. The application of fiber optic sensors is precisely because fiber optic sensors have so many advantages, making their application fields very extensive, involving many fields such as petrochemicals, electricity, medicine, uhandisi wa kiraia, nk.

FJINNO’s fiber optic sensors are fully capable of meeting the higher demands of the high-end market for ultra long distance, ultra high precision, and ultra high sensitivity that cannot be achieved by electrical sensing and general fiber optic sensing.

Compared with traditional sensing technologies, fiber-optic sensors have the following major advantages:

1. Nyepesi, muundo wa kompakt, and easy to reuse multiple times;

2. Resistance to harsh environments, kuingiliwa kwa sumakuumeme, na kutu kwa kemikali;

3. At the sensing point, there is no need for electricity and long-distance distributed sensing is possible;

4. Can be mass-produced at low cost

After fiber optic communication, fiber optic sensing has also ushered in important development opportunities. It has broad and enormous application value in security, kijeshi, oil/gas, electricity, na utafiti wa kisayansi, and its future is limitless.

The transmission fiber for kipimo cha joto la fiber optic is generally quartz fiber, which has the characteristics of corrosion resistance and long service life, and can usually serve for 30 miaka. Taking into account the cost of the sensor itself and future maintenance costs, the use of fiber optic sensors can greatly reduce the final operating cost of the entire project.

Compared with electronic systems, the advantages of fiber optic systems are mainly reflected in the high safety, utulivu mzuri, and long lifespan of sensors. The main application areas are power systems (chini ya ardhi, mistari ya juu), mifumo ya ulinzi wa moto (traffic tunnels), madaraja, kemikali za petroli (mabomba, stations/valve chambers), uhifadhi wa maji, nk. Kwa sasa, the most popular technology is fiber optic iliyosambazwa utambuzi wa vibration, which is applied in various security fields. In some niche markets, technologies such as active/passive infrared targeting, ulengaji wa laser, leaky cables, and vibrating cables have gradually been replaced. Fiber optic sensors have a simple structure, usahihi wa juu, unyeti mkubwa, and are easy to implement in many environments, making them currently very popular.

Disadvantages of non-contact temperature sensors: 1. They are easily affected by environmental factors, such as thermal radiation. 2. They are not easy to achieve long-term continuous measurement of targets.

Advantages of contact temperature sensors: stable measurement and high accuracy; The disadvantage of non-contact temperature sensors is, kwa upande wake, the disadvantage of contact sensors.

Thermal infrared sensor: The advantage is that it can be operated at room temperature, and wavelength dependence does not exist, making it inexpensive; The disadvantage is low sensitivity and slow response.

Quantum type infrared sensor: Its advantages are high sensitivity and fast response; The disadvantages are that it must be cooled (liquid nitrogen), wavelength dependent, and expensive.

Ultrasonic sensor: Its advantages include high frequency, short wavelength, small diffraction phenomenon, especially good directionality and the ability to become rays and propagate in a directional manner; The disadvantage is the presence of triangulation errors, which are easily affected by noise.
