The OFSCN® Fiber Bragg Grating Temperature Sensing Fire Detector is a specialized solution designed for high-reliability fire alarm systems and linear temperature detection. Unlike traditional electronic fire detectors, these sensors utilize FBG technology, making them immune to electromagnetic interference (EMI) and suitable for harsh environments.

Technical Overview

These detectors leverage full metal encapsulation (seamless stainless steel tubes) to ensure rapid thermal response and mechanical protection. They can be configured as either single-point sensors or multi-point linear arrays.

Key Features and Specifications:

  • Encapsulation: Seamless stainless steel tube for maximum durability and chemical resistance.
  • Measurement Range: Depending on the specific model, these sensors can operate in environments ranging from -200°C up to 800°C.
  • Response Speed: The small diameter (typically 0.9mm to 1.1mm) ensures a very low thermal mass for fast detection of temperature spikes.
  • Customization: Fully customizable lengths (from centimeters to dozens of meters) and sensing point intervals.

Product Selection Based on Temperature:

Depending on the maximum temperature requirements of your fire detection environment, we offer several specialized versions:

  1. OFSCN® 300°C Fiber Bragg Grating Temperature Sensor
    • Suitable for standard industrial fire monitoring.
    • Standard diameter: 0.9mm.
  2. OFSCN® 500°C Fiber Bragg Grating Temperature Sensor
    • Designed for medium-high temperature industrial processes.
  3. OFSCN® 800°C Fiber Bragg Grating Temperature Sensor
    • Used for extreme conditions where early fire detection in high-heat zones is critical.
