Applications of Fiber optic temperature measurement in Transformers, Switchgear, MRI, Semiconductors, and Healthcare -INNO

Fiber optic temperature measurement технологи, particularly fluorescent fiber optic temperature sensors, has gained widespread attention and application in recent years due to its numerous advantages. Below is a detailed introduction to its principles, давуу тал, and applications in fields such as transformers, switchgear, MRI, semiconductors, and healthcare.

Principle of Fluorescent Fiber Optic Temperature Sensors

Fluorescent fiber optic temperature sensors are advanced devices that measure temperature based on the principle of fluorescence. The core of the sensor is optical fibers coated with fluorescent materials. When exposed to light, typically from a laser, the fluorescent material becomes excited and emits fluorescence. The intensity and wavelength of the emitted fluorescence are temperature-dependent. An optical detector captures the fluorescence and analyzes its characteristics, and the sensor’s software interprets the data to provide precise temperature readings.

Advantages of Fluorescent Fiber Optic Temperature Sensors

Immunity to Electromagnetic Interference: Unlike traditional electrical sensors, fluorescent fiber optic temperature sensors rely on optical signals for temperature measurement. They are unaffected by electromagnetic fields, making them ideal for environments with high electromagnetic interference (EMI), such as substations and switchgear locations.

High Accuracy and Resolution: These sensors can detect minute temperature changes, offering highly accurate and reliable temperature readings. For example, some fluorescent fiber optic temperature sensors achieve accuracy within ±0.2°C and a resolution of 0.1°C.

Wide Temperature Range: They can operate effectively across a broad temperature spectrum, from cryogenic levels to high-temperature industrial applications, meeting the temperature measurement needs of various industries.

Durability and Longevity: Constructed with optical fibers and fluorescent materials, these sensors exhibit long-term stability and minimal maintenance requirements, ensuring prolonged service life.

Compact Size and Flexible Installation: The sensor probes are small in size, enabling measurement of hard-to-reach hotspots. They can be directly installed in confined spaces within equipment for real-time temperature monitoring. Their flexible installation methods simplify deployment in different application scenarios.

Applications in Transformers

In power transformers, temperature is a critical parameter reflecting operational status. Fluorescent fiber optic temperature sensors are immune to electromagnetic interference and high-voltage environments, making them suitable for monitoring hotspot temperatures in transformer windings. By installing these sensors in transformer windings, real-time temperature data can be obtained. This allows operators to adjust transformer load and operating conditions promptly, preventing overheating and extending the transformer’s lifespan.FJINNO’s fluorescent fiber optic temperature sensors are being developed in collaboration with leading transformer manufacturers to meet the demand for intelligent grid temperature monitoring of power and distribution equipment.

Applications in Switchgear

Switchgear is essential equipment in power systems, and its operating temperature directly impacts reliability. Fluorescent fiber optic temperature sensors provide cost-effective solutions for continuous real-time monitoring of switchgear temperatures at critical contact points. They can quickly detect overload and fault conditions, enabling timely maintenance and reducing equipment downtime. FJINNO IF-C series signal conditioners support analog outputs and RS-485 Modbus communication, facilitating integration with existing PLCs and monitoring software. These optical temperature sensors deliver years of reliable performance, ensuring the safe and efficient operation of switchgear.

Applications in MRI

Magnetic resonance imaging (MRI) equipment operates in high-magnetic-field environments where conventional temperature sensors are often ineffective. Fluorescent fiber optic temperature sensors, however, are unaffected by magnetic fields and provide high-precision temperature measurements. They are widely used in life sciences and patient monitoring applications. FJINNO offers single and multi-channel fiber temperature probes for MRI, NMR, and RF environments, including low-cost disposable probes with rapid response and exceptional accuracy. These probes enable real-time temperature monitoring during MRI scans, ensuring patient safety and improving imaging quality.

Applications in Semiconductors

In semiconductor manufacturing, precise temperature control is critical during processes such as wafer fabrication and chip packaging. Fluorescent fiber optic temperature sensors can monitor the temperature of semiconductor chucks in real time, ensuring stable process temperatures and enhancing product yield and quality. Their non-conductive properties also prevent interference with semiconductor production equipment and processes.

Applications in Healthcare

Fluorescent fiber optic temperature sensors are widely used in minimally invasive medical procedures. Their small probes can be inserted into the human body to monitor internal tissue temperatures in real time. This enables precise temperature control during procedures such as laser ablation and cryotherapy, minimizing tissue damage and improving treatment outcomes. Additionally, these sensors are used in medical research to study temperature changes in biological systems, providing valuable data for medical research and clinical practice.

In summary, fluorescent fiber optic temperature sensors possess numerous advantages, such as immunity to electromagnetic interference, өндөр нарийвчлал, wide temperature range, durability, and compact size. These qualities have enabled their broad application in transformers, switchgear, MRI, semiconductors, healthcare, and other fields. As technology advances, fluorescent fiber optic temperature sensors will continue to improve in performance and functionality, opening up broader application prospects across various industries.
