Perguntas frequentes sobre Sensores de temperatura de fibra óptica

What advantages do fiber optic sensors offer over traditional temperature monitoring?

Sensores de temperatura de fibra óptica provide complete electromagnetic immunity, tornando-os ideais para ambientes de alta tensão. Unlike RTD or thermocouple sensors, they don’t require electrical connections to the measurement point, eliminating safety risks and improving measurement accuracy in electrically noisy environments.

Quantos pontos de temperatura podem ser monitorados com um sistema?

Nosso sistemas de monitoramento de fibra óptica apoiar 1-32 temperature measurement points per unit. Multiple systems can be networked for large installations requiring hundreds of monitoring points across transformer fleets.

What is the typical installation process for fiber optic sensors?

Transformer fiber optic sensors are installed through existing temperature probe ports or custom-drilled access points. The fiber optic cable is routed to the control room where the interrogation unit processes temperature data. A instalação normalmente requer 4-8 hours per transformer depending on complexity.

How does fiber optic technology ensure measurement accuracy?

The system uses fluorescence decay time measurement principle, where temperature changes affect the decay characteristics of fluorescent material at the fiber tip. This provides inherently accurate temperature measurement unaffected by electromagnetic fields or electrical noise common in transformer environments.

What maintenance is required for fiber optic temperature systems?

Sensores de fibra óptica require minimal maintenance due to their passive nature. Annual calibration verification and periodic fiber optic cable inspection are recommended. The absence of electrical components in the sensing element ensures long-term stability and reliability.
