Continuous distributed all-fiber cable temperature measurement system introduction:
The continuous distributed all-fiber cable temperature measurement system uses advanced fiber Raman spectroscopy, optical wavelength division multiplexing, optical time domain reflectometry, high frequency signal acquisition, and weak signal processing to achieve long-distance laying of optical fibers. Point temperature monitoring in real time. The system can also realize fire and dangerous fire linkage.
The temperature of the optical fiber or optical cable used in this series of products can work in harsh environments such as high voltage, strong corrosion, nuclear radiation, and strong electromagnetic interference. The advantages of the optical fiber are strong and durable, and it is easy to network.
An optical fiber can provide information on tens of thousands of measurement points, and installation is quick and easy and cost-effective. The system provides real-time temperature information for the distribution of optical fibers, and graphically displays each measurement object. One host can monitor up to 8 fiber optic cables. The system uses standard multimode fiber as a sensor and no customization is required. Fiber optics are both sensors and communication channels, and no other electronics or measuring devices are needed.
Optical fiber has the characteristics of high temperature resistance (high temperature exceeding 700°C), corrosion resistance, electromagnetic resistance, no static electricity, no radiation interference, and long lifespan. It is suitable for all kinds of complex and harsh environments, such as: high pressure, flammable, and humid , corrosion and high temperature environments. The system provides periodic self-monitoring information on fiber health.
The system provides multi-zone, real-time monitoring and alarm functions. Automatic data and alarm transmission. The system supports remote control functions. Friendly man-machine interface, easy to configure system parameters. The system has a built-in Windows-based computer that does not require the use of other computers.
