This topic discusses the OFSCN® 700°C OFDR Micro All-Metal Strain Sensor, a specialized tool for structural health monitoring in extreme environments.

Technical Overview

The OFSCN® 700°C OFDR Micro All-Metal Strain Sensor is designed for distributed strain and stress measurement. Unlike traditional sensors that may fail at high temperatures due to adhesive degradation, this sensor utilizes an all-metal encapsulation.

Key Specifications:

  • Encapsulation: Single-layer elastic alloy tube.
  • Outer Diameter: Ultra-slim 0.6 mm.
  • Fiber Type: Integrated with OFSCN® Gold-coated Optical Fiber, which is essential for maintaining mechanical integrity and signal transmission at 700°C.
  • Measurement Technology: Optimized for Optical Frequency Domain Reflectometry (OFDR), but also compatible with other distributed sensing methods.

Application Logic

Because this sensor has a diameter of only 0.6mm and a high-modulus metal shell, it is specifically suited for:

  1. High-Temperature Environments: Stable operation up to 700°C.
  2. Embedded Sensing: Its small profile allows it to be embedded into composite materials or metal structures without significantly compromising the structural integrity.
  3. High-Definition Sensing: Providing millimeter-level spatial resolution when used with an OFDR interrogator.

If you are considering this for a specific project, could you please clarify the following:

  1. What is the specific material of the structure you intend to monitor?
  2. How do you plan to install the sensor (e.g., surface bonding, welding, or embedding)?
