Key Advantages of 광섬유 온도 센서

Fiber optic temperature sensors outperform traditional thermocouples in critical applications due to:

• Immunity to EMI: Unaffected by electromagnetic interference, ideal for industrial/military environments.
• High Accuracy: ±0.1°C precision vs. thermocouples’ ±1-2°C range.
• Long-Distance Monitoring: Measure up to 10km away without signal loss.
• Intrinsic Safety: No electrical components – perfect for explosive/flammable settings.
• Multipoint Sensing: Monitor 100+ points on single fiber vs. individual thermocouple wiring.

Fluorescent Fiber Optic Sensor Benefits

Advanced fluorescent technology adds unique capabilities:

• Self-Referencing: Built-in calibration eliminates drift issues common in thermocouples.
• Chemical Immunity: Withstands corrosive environments destroying metal thermocouples.
• Nanosecond Response: 100x faster reaction than Type K thermocouples.
• MRI Compatibility: Safe for medical imaging where metal sensors fail.
• Lifetime Sensing: Measures temperature through phosphor decay characteristics.

Application Domination

Fiber sensors excel where thermocouples struggle:

• High-voltage substations (no arcing risk)
• Microwave sterilization processes
• Oil/gas downhole monitoring
• Aerospace composite curing
• Bioreactor control systems
