FAQ – Frequently Asked Questions
What are the main advantages of fluorescent fiber optic temperature measurement systems?
Fluorescent fiber optic temperature measurement systems offer several key advantages: complete immunity to electromagnetic interference, excellent electrical insulation properties (suitable for high voltage environments), high measurement accuracy (typically ±0.3℃), ability to operate in explosive environments, remote monitoring capabilities, long service life (typically 10+ years), and minimal maintenance requirements due to passive sensor design.
How do fluorescent fiber optic sensors work?
Fluorescent fiber optic sensors work based on the temperature-dependent fluorescence lifetime principle. When excited by light pulses, fluorescent materials emit light with decay characteristics that vary with temperature. The sensor measures the fluorescence decay time to determine temperature. This optical measurement method eliminates electrical connections at the sensing point, providing complete electrical isolation.

These systems are ideal for high voltage electrical equipment including power transformers, switchgear, motors, generators, and overhead transmission lines. They excel in environments with strong electromagnetic fields, confined spaces, explosive atmospheres, and where traditional sensors would pose safety risks or provide unreliable measurements.
How accurate are fluorescent fiber optic temperature sensors?
Modern fluorescent fiber optic temperature sensors typically achieve accuracy within ±0.3℃ to ±1℃ depending on the specific application and manufacturer.
What is the typical installation process for these systems?
Installation involves placing miniature fluorescent sensors (typically 1-2mm diameter) at critical measurement points, connecting them via optical fiber to a central processing unit, and configuring the monitoring software. The sensors can be permanently embedded in equipment during manufacturing or retrofitted during maintenance shutdowns.
How do these systems compare in cost to traditional temperature monitoring methods?
While initial investment may be higher than conventional sensors, fluorescent fiber optic systems offer superior total cost of ownership due to minimal maintenance requirements, extended service life, and reduced downtime risks. The prevention of single equipment failure can justify the entire system investment.
What maintenance is required for fluorescent fiber optic temperature systems?
