The Embedded Sensing Expert: OFSCN® Micro All-Metal Strain Sensor, Empowering the Era of "Smart Materials"

In sectors such as aerospace, wind energy, and high-pressure vessel manufacturing, composite materials are rapidly replacing traditional metals. However, how do we perceive the "real heartbeat" inside these materials? How do we capture the precise moment a micro-crack initiates?

The OFSCN® Micro All-Metal Strain Sensor, developed by Beijing Dacheng Yongsheng Technology Co., Ltd., has become the globally recognized "Embedded Sensing Expert" thanks to its ultra-fine 0.6 mm profile. It is transforming passive materials into "Digital Intelligent Structures" with self-sensing capabilities.

1. 0.6 mm: The Ultimate Dimension for "Non-Destructive Embedding"

During the manufacturing of composite materials (such as carbon fiber or fiberglass), a sensor that is too bulky will disrupt the continuity of the fibers, creating a structural weak point.

• Ultra-Fine Diameter: With an outer diameter of only 0.6 mm—roughly the thickness of a needle tip—it can be easily embedded between fiber plies with virtually zero interference to the material's original mechanical properties.
• High-Elasticity Alloy: Encapsulated in a single-layer special alloy tube, the sensor possesses high radial stiffness. It can withstand the intense compaction pressures of composite molding while achieving perfect strain coupling with the host material.

2. Why is it the Optimal Partner for OFDR Technology?

To achieve millimeter-level high-spatial-resolution monitoring, OFDR (Optical Frequency Domain Reflectometry) is the premier choice. The design details of the OFSCN® sensor are engineered to extract every bit of potential from OFDR technology:

1. High-Modulus Transfer: Unlike plastic jackets, the all-metal tube has a high elastic modulus. This ensures that even micro-strains at the micron level are transferred linearly and truthfully to the internal Silicon Dioxide (SiO2) fiber core.
2. End-point Anchoring Technology: The sensor comes with integrated anchoring devices pre-installed at the factory. This solves the industry-wide challenge of "fiber slippage" within metal tubes, ensuring zero-latency strain capture and high repeatability.
3. Ultra-Wide Temperature Coverage: Depending on the application, versions are available for 85℃, 200℃, 300℃, and up to a maximum of 700℃, meeting the needs of everything from standard composite curing to aerospace engine component testing.

3. Cutting-Edge Applications Across Borders

The OFSCN® Micro Strain Sensor serves top-tier engineering projects worldwide:

• Aerospace: Embedded in composite wing spars to monitor structural fatigue and strain gradients in real-time during flight.
• Wind Energy: Monitoring load distribution in ultra-long blades to prevent catastrophic fractures caused by material aging.
• Hydrogen Safety: Embedded in the winding layers of high-pressure hydrogen tanks (Type IV) to sense subtle liner deformations, ensuring energy storage safety.
• Civil Engineering Research: Embedded in critical structural members of bridges or buildings to monitor dynamic responses under seismic or load impacts.

4. Conclusion: Defining the Depth of Perception

The industrial competition of the future is a competition for data. Beijing Dacheng Yongsheng Technology Co., Ltd., through the OFSCN® brand, provides global clients with a technical solution that allows sensors to "disappear" inside the material itself.

If you are looking for a strain sensing solution that provides millimeter-level precision without compromising material strength, the OFSCN® Micro All-Metal Sensor is your ultimate choice.
