1. Product Overview of OFSCN® 85°C OFDR SST Distributed Temperature Sensor
The OFSCN® 85°C OFDR SST Distributed Temperature Sensor is a miniaturized sensing unit specifically engineered for millimeter-scale spatial resolution temperature field monitoring. Encapsulated in a single-layer seamless metal tube, it features a unique "Zero-Strain Interference" design that ensures the optical fiber remains mechanically decoupled from the tube's thermal expansion. Combined with its "Ultra-Low Thermal Resistance," this sensor can capture transient temperature changes, making it the ideal choice for battery thermal runaway analysis, precision medical devices, aerospace, and industrial R&D applications using OFDR (Optical Frequency Domain Reflectometry).

4. Key Technical Advantages of OFSCN® 85°C OFDR SST Distributed Temperature Sensor
4.1 "Zero-Strain Interference" Design
In OFDR measurements, temperature and strain can cause cross-sensitivity. OFSCN® utilizes a proprietary internal clearance design that allows the fiber to remain in a "relaxed" state within the 0.9 mm tube. When the metallic tube undergoes thermal expansion, the strain is not transmitted to the fiber core. This ensures that the OFDR demodulated signal reflects pure temperature shifts, significantly enhancing measurement accuracy.
4.2 "Ultra-Low Thermal Resistance"
The all-metal seamless tube structure eliminates the need for thick plastic or polymer jackets. Due to the high thermal conductivity of the metal and the ultra-fine diameter, the sensor's thermal equilibrium time is reduced to milliseconds. When monitoring sudden thermal events, such as a power battery short circuit, this sensor provides a near-instantaneous synchronous response.
