How Distributed Fiber Optic Temperature Sensing Works for Fire Detection

Tecnologia Central: Princípio de dispersão Raman

Sensor de temperatura distribuído (ETED) analisa luz retroespalhada com:

• Precisão de ±0,5°C via IEC 61757-2-1 processamento certificado
• 2m resolução espacial com taxa de amostragem de 1 Hz
• 10alcance de km por unidade de interrogatório

Componentes de sistema de nível industrial

Papel	Especificações	Certificação
Unidade Laser	1550nm, 10mW	Classe 1M da FDA
Cabo de detecção	Armadura de aço inoxidável	Classificação IP68

Fluxo de Trabalho Operacional

1. Pulsos de laser (1largura) enviado através de fibra
2. Backscatter analisado por meio de detectores APD
3. Perfis de temperatura mapeados para layouts BIM/CAD

Principais diferenciadores vs.. Sistemas Tradicionais

• ▶️ Tempo de resposta de 5s versus 30s+ para detectores de fumaça
• ▶️ 0% alarmes falsos em ISO 7240-42 testes
• ▶️ Vida útil de 20 anos (contra 5-7 anos para sensores pontuais)

Vantagens dos sensores distribuídos de fibra óptica no monitoramento de temperatura
