फाइबर ऑप्टिक ग्रेटिंग तापमान सेंसर का सर्वश्रेष्ठ निर्माता

In the current situation of power equipment, such as transformer temperature measurement, electrical sensors (such as platinum resistors) are mainly used. One wire is connected to one sensor, and the signal is an electrical signal, which is easily affected by strong electricity and strong magnetism. It is also limited to use in flammable, explosive and other situations; In power applications with strong electromagnetic interference and high insulation requirements, FJINNO’s independently developed fiber optic temperature measurement system has been widely used in various temperature measurement fields.

What are the advantages of फाइबर ऑप्टिक झंझरी सेंसर

As a type of passive fiber optic device, fiber Bragg gratings have advantages such as resistance to electromagnetic interference, उच्च तापमान, और छोटा आकार. Fiber Bragg grating sensors mainly use fiber Bragg gratings, and the sensor signal made of fiber Bragg gratings is wavelength modulated, with strong anti-interference ability. The measurement signal is not affected by factors such as fiber loss, light source fluctuations, and detector aging. It is easy to combine wavelength division multiplexing technology to form a fiber Bragg grating sensing network, achieving distributed multi-point real-time online sensing. It is widely used in the measurement of physical quantities such as temperature, छानना, और दबाव. Temperature measurement is one of the most important applications of fiber optic grating sensors. Electronic temperature sensors such as thermocouple sensors and thermistor sensors have disadvantages such as poor resistance to electromagnetic interference, poor stability, and slow response speed. They are suitable for narrow environments and cannot be used in harsh environments. फाइबर ऑप्टिक ग्रेटिंग तापमान सेंसर में उच्च संवेदनशीलता जैसे फायदे हैं, छोटे आकार का, resistance to electromagnetic radiation, मजबूत स्थिरता, और लंबी सिग्नल ट्रांसमिशन दूरी, उन्हें विभिन्न प्रकार के वातावरणों के लिए उपयुक्त बनाना.

फाइबर ऑप्टिक ग्रेटिंग तापमान सेंसर की विशेषताएं क्या हैं?

फाइबर ब्रैग ग्रेटिंग तापमान सेंसर एक सेंसर है जो आंतरिक संवेदनशील तत्व से परावर्तित प्रकाश संकेत के केंद्रीय तरंग दैर्ध्य बदलाव द्वारा तापमान का पता लगाता है – the fiber Bragg grating. सतह जैसे विभिन्न पैकेजिंग विकल्पों के साथ स्थापना संरचनाएं, अंतर्निहित, and immersion. Due to the fact that fiber optic grating temperature sensors use light waves to transmit information, and optical fibers are electrically insulated and corrosion-resistant transmission media, वे मजबूत विद्युत चुम्बकीय हस्तक्षेप से डरते नहीं हैं और बाहरी विद्युत चुम्बकीय क्षेत्र को प्रभावित नहीं करते हैं. This makes them convenient and effective for monitoring in various large-scale electromechanical, पेट्रो, metallurgical high-pressure, मजबूत विद्युत चुम्बकीय हस्तक्षेप, flammable, विस्फोटक, and highly corrosive environments, with high reliability and stability. इसके अलावा, the फाइबर ऑप्टिक झंझरी तापमान के माप परिणाम सेंसर में अच्छी पुनरावृत्ति क्षमता होती है, making it easy to form various forms of fiber optic sensing networks and can be used for absolute measurement of external parameters. Multiple gratings can also be written into a single optical fiber to form a sensing array, achieving quasi distributed measurement.

Fiber optic grating sensors not only have the advantages of ordinary fiber optic sensors, such as electromagnetic resistance, संक्षारण प्रतिरोध, उच्च तापमान प्रतिरोध, no electricity, no heat generation, flame resistance, विस्फोट विरोधी, हल्का वजन, small volume, and safe operation in harmful or dangerous environments, but also have unique advantages: fiber optic sensors are easy to couple and have low coupling loss; मजबूत हस्तक्षेप विरोधी क्षमता, integrating sensing and transmission, and having stronger multiplexing ability, making it easy to form a sensing network; It has a wide range of measurement objects and is easy to achieve multi parameter sensing measurement.

Application Fields of Fiber Bragg Grating Sensors

Fiber optic grating sensors have various installation methods, such as surface mounted and embedded, and can be widely used for distributed temperature monitoring and measurement of civil engineering structures such as bridges, बांधों, सुरंगों, as well as quasi distributed accurate temperature measurement of large facilities or equipment in the fields of chemical, शक्ति, सैन्य, एयरोस्पेस, fire protection, खनन, वगैरह. They can also be used for temperature sensing fire detection and automatic alarm in oil tanks and highway tunnels.
