The Fiber Bragg Grating (FBG) Temperature Sensing Fire Detector is a specialized sensor designed for high-reliability fire alarm systems, utilizing the wavelength-shift principle of Fiber Bragg Gratings to detect temperature changes.

Based on the technical specifications for this product line, here are the key technical advantages of the OFSCN® solution:

Technical Features

  1. Full Metal Encapsulation: Unlike traditional sensors that may use adhesives or polymers, these detectors utilize a seamless stainless steel tube encapsulation. This ensures high mechanical strength and prevents degradation in harsh environments.
  2. Multi-point Sensing: A single fiber can integrate multiple FBG sensing points, allowing for “linear” fire detection over long distances (e.g., in cable tunnels or warehouses) without the need for complex wiring.
  3. Intrinsic Safety: Being entirely optical, the sensor is immune to electromagnetic interference (EMI) and is inherently explosion-proof, making it ideal for oil and gas or chemical storage applications.

Technical Consultation

To provide a more precise recommendation for your fire detection project, could you please clarify:

  1. Maximum Alarm Temperature: What is the maximum temperature the sensor needs to withstand during a fire event (e.g., 100°C, 300°C, or higher)?
  2. Detection Topology: Do you require a single sensing point per cable, or a multi-point “string” configuration to cover a specific length?
