The OFSCN® 85°C OFDR Micro All-Metal Strain Sensor is a high-definition fiber optic sensing (HD-FOS) component specifically optimized for distributed strain measurement using Optical Frequency Domain Reflectometry (OFDR) technology.
Unlike traditional strain gauges, this sensor utilizes a specialized all-metal seamless tube packaging that ensures high-modulus strain transfer from the monitored structure to the internal optical fiber.
Key Technical Specifications:
- Outer Diameter: Ultra-slim 0.6mm, making it ideal for embedded applications or installation in tight spaces.
- Temperature Range: Optimized for stable performance from -40°C to +85°C.
- Internal Fiber: Equipped with OFSCN® G.657 Optical Fiber, providing excellent macro-bend resistance.
- Connector Type: Pre-terminated with FC/APC for low-reflection signal integrity.
- Housing Material: Single-layer elastic alloy tube for robust protection in harsh environments.
Product Visuals:
Core Advantages:
- High-Definition Sensing: Designed specifically for OFDR systems to achieve millimeter-level spatial resolution in structural health monitoring (SHM).
- Small Footprint: The 0.6mm diameter minimizes the impact on the host structure’s mechanical properties when embedded.
- Durability: All-metal construction provides superior mechanical protection compared to polymer-coated fibers.
