Mejor cima 10 Fabricantes de sensores de temperatura de fibra óptica: Una guía completa

Sensores de temperatura de fibra óptica (PIE) represent a significant advancement in temperature measurement technology, offering unique advantages over traditional electronic sensors, especially in challenging environments like high-voltage equipment, procesos industriales, y aplicaciones médicas. Choosing the right manufacturer is crucial for ensuring accuracy, fiabilidad, 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.

¿Qué son los sensores de temperatura de fibra óptica??

Sensores de temperatura de fibra óptica (PIE) are devices that use fibra óptica para medir la temperatura. 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, tiempo de caída de la fluorescencia, or scattering characteristics) are detected and analyzed by an interrogation unit (or reader) to determine the temperatura en el sensor ubicación(s).

Why Use Fiber Optic Temperature Sensors?

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

• Inmunidad a la interferencia electromagnética (EMI/RFI): Being dielectric, they are unaffected by electrical noise, perfecto para entornos de alto voltaje (transformadores de potencia, aparamenta) or strong magnetic fields (resonancia magnética, aceleradores de partículas).
• Seguridad intrínseca: No electrical current means no spark risk, vital for hazardous areas (aceite & gas, minería, plantas quimicas).
• Tamaño pequeño y ligero: 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), presión alta, corrosión, y radiación.
• Alta precisión & Resolución: Offer precise mediciones de temperatura with excellent stability.

¿Cómo funcionan los sensores de temperatura de fibra óptica??

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

• Rejillas de fibra de Bragg (FBG): Reflects a specific light wavelength that shifts with temperature (y colar). Used for quasi-distributed point sensing. Companies like Luna Innovations, HBK, Atención, Sentea, Proximion utilize this.
• Dispersión Raman: The intensity ratio of temperature-dependent Raman scattered light is measured. Ideal para Detección de temperatura distribuida (EDE) a lo largo de toda la longitud de la fibra. Yokogawa is a key player here.
• Arseniuro de galio (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.
• Fluorescencia Decay Time: A fluorescent material at the fiber tip is excited by light, and its fluorescence decay time changes with temperature. Utilized by FJINNO, Energía Avanzada (Luxtron), and Tempsens.
• Otros métodos: Interferometry (Fabry-Perot), dispersión de brillo (also used for DTS), and others exist for specific applications.
