1. Fluorescence Fiber Optic Temperature Sensor ⭐ Editor’s Top Pick

What is Fluorescence Fiber Optic Temperature Sensing Technology?

The fluorescencyjny, światłowodowy czujnik temperatury operates on the principle of temperature-dependent fluorescence decay in rare earth materials. When excited by UV or blue light, rare earth phosphors emit fluorescence with a decay time that varies predictably with temperature. This absolute measurement method eliminates the need for calibration throughout the sensor’s lifetime.

Unlike conventional electrical sensors, the fluorescence temperature sensor uses light as the measurement medium, transmitted through optical fiber. The sensing element contains no electronic components, making it inherently immune to electromagnetic interference and electrically isolated from the measurement system.

Why Fluorescence Fiber Optic is the Best Choice for High Voltage Power Equipment

The complete electrical isolation provided by światłowodowe czujniki temperatury makes them uniquely suited for high voltage applications. The glass fiber offers dielectric strength exceeding 100kV, allowing direct installation in transformer windings and switchgear without expensive isolation barriers.

In strong electromagnetic fields found inside transformers and generators, the fluorescence sensor delivers accurate measurements unaffected by EMI that would cause false readings in conventional RTD or thermocouple systems. The intrinsically safe design eliminates spark risks in hazardous locations without requiring explosion-proof housings.

2. PT100/PT1000 Platinum RTD Temperature Sensor

PT100 Working Principle

The PT100 temperature sensor exploits the positive temperature coefficient of platinum metal resistance. W temperaturze 0°C, the standard resistance measures exactly 100Ω, increasing linearly with temperature. This predictable relationship enables accurate temperature calculation through simple resistance measurement.

PT100 Technical Specifications and Accuracy Classes

• Class AA: ±(0.1+0.0017|T|)°C – Laboratory precision
• Klasa A: ±(0.15+0.002|T|)°C – Industrial high accuracy
• Klasa B: ±(0.3+0.005|T|)°C – General industrial use
• Wiring: 2-drut (economy), 3-drut (standard), 4-drut (precyzja)

PT100 Advantages

The platinum RTD sensor offers excellent linearity and high accuracy conforming to IEC 60751 standardy międzynarodowe. Good interchangeability allows sensor replacement without system recalibration. The measurement range extends from -200°C to +850°C, covering most industrial applications.

PT100 Practical Limitations

Copper lead wire resistance affects measurement accuracy, requiring 3-wire or 4-wire configurations for compensation. Czujniki rezystancyjne are susceptible to EMI interference in electrically noisy environments. Periodic calibration every 1-2 years is necessary to maintain accuracy. High voltage insulation becomes complex and expensive. Response time typically ranges from several seconds, slower than thermocouples.

PT100 in Transformer Temperature Measurement

Czujniki PT100 serve well for measuring transformer top oil and bottom oil temperatures in conventional applications. Jednakże, winding temperature measurement presents significant technical challenges:

• Izolacja wysokiego napięcia: Requires expensive high-voltage insulation bushings
• EMI Interference: Copper wiring susceptible to transformer internal electromagnetic fields
• Oil Aging: Long-term oil immersion degrades insulation
• Konserwacja: Calibration requires transformer shutdown

These limitations explain why transformer winding hot spot monitoring increasingly adopts fluorescence fiber optic technology, eliminating high voltage insulation complexity, EMI interference, and reducing lifecycle maintenance costs.
