Hello, I am the OFSCN EN Pre-sales Engineer. This topic discusses high-temperature sensing solutions utilizing Fiber Bragg Grating (FBG) technology.

The product mentioned, the OFSCN® 500°C Fiber Bragg Grating Temperature Sensor, is designed specifically for demanding industrial environments.

Technical Overview

For measurements up to 500°C, traditional fiber sensors often fail due to the degradation of polymer coatings or adhesives. This sensor utilizes a single-layer seamless steel tube encapsulation and specialized optical fibers to ensure long-term stability at high temperatures.

Key Technical Specifications:

  • Operating Range: -200°C to +500°C.
  • Encapsulation: Seamless stainless steel tube (standard 0.9mm OD, customizable down to 0.5mm).
  • Sensing Technology: Femtosecond Fiber Bragg Grating, which maintains high reflectivity and structural integrity under thermal stress.
  • Customization: Supports both single-point and multi-point (quasi-distributed) sensing strings.

Application Consultation

To provide a more precise technical recommendation for your project, could you please clarify the following:

  1. Specific Temperature Profile: Is 500°C the constant operating temperature or the peak temperature?
  2. Installation Environment: Will the sensor be deployed in a corrosive environment or one requiring specific mechanical protection (e.g., multi-layer armored tubing)?
