Fiber optic temperatura sensor, Matalinong sistema ng pagsubaybay, Ipinamamahagi fiber optic tagagawa sa Tsina

Executive Summary

Smart temperature sensors, particularly fluorescence fiber optic sensors, significantly reduce downtime in power systems by enabling real-time, high-precision monitoring of critical equipment. These sensors excel in high-voltage environments, resist electromagnetic interference (EMI), and support multi-channel measurements, making them ideal for transformers, switchgear, and transmission lines. This guide explores their working principles, technical advantages, and why Fuzhou Inno Technology stands out as a top supplier.

Working Principle of Fluorescence Fiber Optic Temperature Sensing

Fluorescence-based fiber optic sensors utilize temperature-sensitive phosphor coatings at the fiber tip. When excited by specific light wavelengths, these materials emit fluorescent signals with decay rates proportional to ambient temperature. This optical measurement method ensures:

• Galvanic isolation from electrical systems
• Immunity to EMI/RFI interference common in substations
• No risk of short circuits even at 500kV+ voltage levels

Key Technical Advantages

1. High-Voltage Endurance

Withstand voltages up to 500kV AC/±700kV DC, perfect for:

• Transformer winding hot-spot monitoring
• Gas-insulated switchgear (GIS) contact temperature tracking

2. Multi-Parameter Monitoring Capability

Parameter	Specification	Benefit
Channels	Up to 24 per system	Simultaneous monitoring of busbars/cables/joints
Accuracy	±0.5°C	Early fault detection in critical assets
Response Time	<1s	Rapid load adjustment during peak demand [8]()

3. Harsh Environment Performance

• IP68 protection for outdoor transmission lines
• -40°C to 300°C operational range
• Corrosion-resistant quartz fiber construction
