How it Works
- Signal Transmission: A DTS system sends a laser light pulse through the PEEK-reinforced fiber optic cable.
- Light Scattering: As the light travels, it scatters in different ways at each point along the fiber, including Raman and Brillouin scattering .
- Temperature-Dependent Scattering: The intensity and frequency of these scattered light signals (specifically the anti-Stokes and Stokes peaks) are temperature-dependent.
- Signal Reception: The DTS system receives these reflections and analyzes the frequency and amplitude of the Raman and Brillouin peaks.
- Temperature Calculation: By processing these signals, the system can determine the temperature at each meter of the fiber, providing a complete temperature profile.
Key Characteristics
- Material: The PEEK (Polyetheretherketone) reinforcement provides superior high-temperature, chemical, and abrasion resistance compared to standard cables.
- Sensing Principle: It operates on the principles of Distributed Temperature Sensing (DTS).
- Sensing Length: DTS systems can monitor temperature over long distances, often up to several kilometers.
- Spatial Resolution: The temperature can be measured with high spatial resolution, typically down to one meter along the cable.
- Environmental Resistance: The PEEK jacketing is ideal for harsh environments where standard cables would fail due to high temperatures or chemical exposure.
Applications
Temperature sensing fiber optic PEEK cables are used in various industrial and safety applications, including:
Temperature sensing fiber optic PEEK cables are used in various industrial and safety applications, including:
