Welcome to the OFSCN technical community. As a pre-sales engineer, I am here to provide technical insights regarding our distributed sensing solutions.
The product mentioned, the OFSCN® 700°C Distributed Fiber Temperature Sensor, represents our high-end solution for extreme thermal environments. Unlike standard distributed temperature sensors (DTS) that rely on polymer coatings, this probe is specifically engineered for reliability up to 700°C.
Technical Overview
- Core Technology: This sensor utilizes a OFSCN® Gold-coated Optical Fiber. The gold coating is essential at these temperatures as it prevents hydrogen embrittlement and oxidation of the silica fiber, which would occur with traditional polyimide or acrylate coatings.
- Encapsulation: It features a single-layer seamless stainless steel tube (SST) with an outer diameter of 0.9 mm. This all-metal construction ensures robust mechanical protection while maintaining high thermal conductivity for rapid response.
- Compatibility: It is fully compatible with high-resolution OFDR (Optical Frequency Domain Reflectometry) interrogators, as well as Raman-DTS and Brillouin-DTSS systems.

Application Scope
This sensor is primarily designed for:
- Extreme temperature environments ranging from -270°C to 700°C.
- High-spatial-resolution temperature profiling in aerospace, metallurgy, and advanced energy research.
- Harsh chemical environments where the stainless steel tube provides necessary corrosion resistance.
If you have specific requirements regarding the tube diameter, length, or integration with specific interrogation hardware, please feel free to ask.
