How to Simulate "Hell" in the Laboratory? — The Role of OFSCN® 700-C-SST in Frontier Scientific Research

In the laboratories of advanced physics, aerospace, and materials science, researchers often need to construct "hellish" extreme environments: supercritical fluids, aerospace engine combustion chambers, or even the cooling boundaries of nuclear fusion experimental devices. These environments share common challenges: extreme heat, high pressure, and intense corrosion.

In an operating condition of 700°C, the ability to obtain high-precision, real-time data determines the success or failure of a research project. The OFSCN® 700-C-SST seamless stainless steel tube high-temperature optical fiber cable, developed by Beijing Dacheng Yongsheng Technology Co., Ltd., is becoming a key tool for global laboratories to break through the limits of perception.

1. The "Perception Paradox" of 700°C Experiments

In scientific research, we face a paradox: to obtain the most accurate data, a sensor must be placed as close as possible to the center of the heat source; however, the closer it is to the center, the more likely the sensor is to fail.

• Traditional Thermocouples: These are often bulky and can disrupt the thermal field distribution of tiny experimental models (flow field interference).
• Ordinary Optical Fiber: Once temperatures exceed 300°C, organic coatings decompose rapidly. The Silicon Dioxide (SiO2) fiber, losing its protection, becomes extremely fragile and prone to micro-cracking.

2. 700-C-SST: "Neural Fibers" Born for Extreme Research

The OFSCN® 700-C-SST is more than just a cable; it is a flexible precision instrument that can span kilometers. How does it empower global research?

A. Extreme Miniaturization, Zero-Interference Monitoring

The outer diameter of the 700-C-SST can be manufactured to be incredibly fine (e.g., 0.6mm or 0.9mm). In complex wind tunnel tests or fluid experiments, this slender seamless stainless steel tube (made of 316L alloy) can easily pass through narrow gaps in experimental setups. It minimizes interference with the original physical flow and temperature fields, ensuring the purity of experimental data.

B. Signal Integrity in "Hellish" Conditions

Through longitudinal laser welding technology, the seamless steel tube provides a fully enclosed vacuum or inert gas environment for the internal Silicon Dioxide (SiO2) fiber. This effectively blocks high-temperature oxidation and hydrogen darkening, allowing the fiber to maintain extremely low signal attenuation and a high signal-to-noise ratio across an ultra-wide temperature range from -200°C to 700°C.

C. Distributed Temperature/Strain Sensing (DOFS)

For researchers, single-point data is rarely enough. When paired with distributed interrogation equipment, the 700-C-SST turns the entire cable into thousands of continuous sensors. This allows you to obtain a complete "temperature gradient curve" or "strain distribution map" inside the equipment, which is critical for validating numerical simulation models (CAE/CFD).

3. Global Applications in Frontier Science

Today, OFSCN® 700-C-SST transcends geographical boundaries, serving strategic research fields worldwide:

• Aerospace: Monitoring thermal cycles of new turbine engine blades and exhaust systems.
• Nuclear Energy Research: Long-term integrity monitoring of reactor cooling loops.
• Deep Earth Exploration: Simulating high-temperature and high-pressure rock physics experiments for geothermal and deep-well drilling.
• New Material R&D: Monitoring thermal expansion and phase transitions of ceramics and alloys during continuous heating at 700°C.
