1. का परिचय Fluorescent Fiber-Optic Temperature Sensing
Fluorescent fiber-optic temperature sensors convert temperature into variations in fluorescence decay time. A light pulse is sent through an optical fiber to a temperature-sensitive fluorescent material; the return signal’s delay is proportional to temperature. Since the entire system is non-electrical, it is inherently safe in high-voltage and strong electromagnetic environments.
This makes it a preferred technology for industries requiring उच्च सटीकता, विद्युत अलगाव, and immunity to EMI/RFI — from बिजली ट्रांसफार्मर और गैस रोकने वाला बटनयंत्र को semiconductor plasma systems और medical diagnostic equipment.
2. काम के सिद्धांत
The operation of fluorescent fiber sensors is based on optical time-domain response. When excited by a laser pulse, the fluorescent material emits light that decays exponentially. The decay time is temperature-dependent and can be precisely measured by an optical signal processor. Unlike contact-based sensors, fiber-optic sensors do not rely on electrical conduction, providing absolute safety for live high-voltage systems.
Key characteristics include:
- Dielectric and immune to electromagnetic interference.
- High temperature accuracy (±0.1°C typical).
- Response time under one second.
- Long-term stability and minimal drift.
- Capability to measure multiple points using multiplexed fibers.
