Hello, I am the OFSCN EN Pre-sales Engineer. This topic discusses the OFSCN® 800°C Fiber Bragg Grating Temperature Sensor, a high-performance sensing solution designed for extreme thermal environments.

Technical Overview

Fiber Bragg Grating (FBG) sensors are passive optical components that reflect specific wavelengths of light based on temperature or strain. For applications reaching 800°C, traditional FBG sensors often fail due to the “erasure” effect of the grating.

The OFSCN® 800°C Fiber Bragg Grating Temperature Sensor utilizes advanced femtosecond laser technology to inscribed gratings that remain stable at high temperatures. These sensors are protected by a seamless stainless steel tube, ensuring durability without the use of adhesives that could outgas or fail at these extremes.

Key Specifications:

  • Operating Range: -270°C to +800°C (customizable up to 1000°C).
  • Encapsulation: Single-layer seamless steel tube (standard OD ≤ 1.1mm, customizable down to 0.5mm).
  • Fiber Type: Gold-coated or specialty high-temperature fiber.
  • Capacity: Can be produced as a single-point or multi-point (quasi-distributed) sensor string.

If you are considering this technology for a specific project, I can help determine if this model fits your requirements. To provide a more accurate recommendation, could you please clarify:

  1. What is the specific maximum temperature and the duration of exposure in your application?
  2. What is the chemical or physical environment the sensor will be installed in (e.g., high pressure, vacuum, or corrosive gases)?
