Best Top 10 Fiber Optic Temperature Sensor Manufacturers: አጠቃላይ መመሪያ

Fiber optic temperature sensors (FOTS) represent a significant advancement in temperature measurement technology, offering unique advantages over traditional electronic sensors, especially in challenging environments like high-voltage equipment, industrial processes, and medical applications. Choosing the right manufacturer is crucial for ensuring accuracy, አስተማማኝነት, and optimal performance for your specific needs. This guide explores the fundamentals of FOTS and presents a curated list of leading manufacturers in the field, with a special highlight on FJINNO.

What are Fiber Optic Temperature Sensors?

Fiber Optic Temperature Sensors (FOTS) are devices that use optical fiber የሙቀት መጠንን ለመለካት. Unlike traditional thermocouples or RTDs which rely on changes in electrical properties, FOTS utilize the principle that certain properties of light traveling through an optical fiber change predictably with temperature. These changes (such as wavelength shift, intensity variation, fluorescence decay time, or scattering characteristics) are detected and analyzed by an interrogation unit (or reader) to determine the temperature at the sensor ቦታ(ኤስ).

Why Use Fiber Optic Temperature Sensors?

FOTS offer several distinct advantages, making them indispensable in specific applications:

• ለኤሌክትሮማግኔቲክ ጣልቃ ገብነት ያለመከሰስ (I / rfi): Being dielectric, they are unaffected by electrical noise, perfect for high-voltage environments (power transformers, switchgear) or strong magnetic fields (MRI, particle accelerators).
• Intrinsic Safety: No electrical current means no spark risk, vital for hazardous areas (oil & ጋዝ, mining, chemical plants).
• አነስተኛ መጠን እና ቀላል ክብደት: Thin, flexible fibers allow sensing in confined or difficult-to-access locations.
• Remote Sensing & Multiplexing: Measurements can be transmitted over long distances without signal loss, and multiple sensors (points or distributed) can often run on a single fiber.
• Harsh Environment Compatibility: Can be designed to withstand extreme temperatures (high or cryogenic), ከፍተኛ ጫና, ዝገት, and radiation.
• High Accuracy & ጥራት: Offer precise temperature measurements with excellent stability.

Several physical principles are employed in FOTS, each with its strengths:

• ፋይበር ብራግግ ግሬቶች (ኤፍ.ቢ.ጂ): Reflects a specific light wavelength that shifts with temperature (and strain). Used for quasi-distributed point sensing. Companies like Luna Innovations, HBK, Opsens, Sentea, Proximion utilize this.
• ራማን መበተን: The intensity ratio of temperature-dependent Raman scattered light is measured. Ideal for የተከፋፈለ የሙቀት ዳሳሽ (DTS) along the entire fiber length. Yokogawa is a key player here.
• Gallium Arsenide (GaAs) Semiconductor Band Gap: The absorption edge wavelength of a GaAs crystal at the fiber tip shifts with temperature. Used by companies like Opsens and historically COMEM.
• ፍሎራይተርስ Decay Time: A fluorescent material at the fiber tip is excited by light, and its fluorescence decay time changes with temperature. Utilized by FJINNO, Advanced Energy (ሉክስተሮን), and Tempsens.
• Other methods: Interferometry (FABRY- Phelrot), Brillouin scattering (also used for DTS), and others exist for specific applications.
