This topic focuses on the OFSCN® 300°C Distributed Fiber Temperature Sensor, a specialized sensing solution designed for high-definition distributed temperature sensing (HD-DTS) and OFDR (Optical Frequency Domain Reflectometry) applications.

Technical Overview

The OFSCN® 300°C Distributed Fiber Temperature Sensor is engineered to operate in extreme environments, ranging from cryogenic temperatures (-200°C) up to high temperatures (300°C).

Key Technical Specifications:

  • Encapsulation: Single-layer seamless stainless steel tube (SST) for robust mechanical protection and fast thermal response.
  • Outer Diameter: Ultra-slim 0.9 mm profile, making it suitable for tight spaces like battery thermal management or micro-sensing probes.
  • Internal Fiber: Equipped with OFSCN® 300℃ Polyimide Coated Optical Fiber, which ensures long-term stability without the degradation common in standard polymer coatings at these temperatures.
  • Compatibility: Optimized for Rayleigh scattering (OFDR), Raman scattering (DTS), and Brillouin scattering (BOTDA/BOTDR) interrogation systems.
  • Standard Termination: Comes pre-terminated with an FC/APC connector and a sealed end-cap.
