W-PD7S Cable Temperature Monitoring System
W-PD7 fault detection of temperature rise to laying in the tested object of distributed optical fiber as medium, high resolution of optical fiber transmission and processing signal analyzer incident and returning to the laser characteristics, to capture data for a hot and fault analyzed the hot temperature effect:
W-PD7 the original import sensor and analyzer, factories ISO9001 certification, in the distributed optical fiber temperature measurement field of applied for 20 years history, stable performance.
In addition, as W-PD7 monitoring principle is a direct measurement Raman scattering light two components, even if the ratio of the optical fiber with time aging, light loss increases, still can effectively eliminate the influence of light loss to ensure continuous temperature measurement precision.
W-PD7 through 1-3, optical fiber sensors can master the article medium voltage, high voltage cables channel the rise of temperature of the state, the convenient user master cable tunnel (or cable trench) internal fire, environmental temperature and the rise of temperature of the cable.
Optical fiber sensor has strong resistance to electromagnetic interference ability, is easy to installation, along the tunnel walls or laying cable tray.
• Check points continuous, it can comprehensive, real-time detection was monitoring objects of different points, monitoring temperature range;
• Not only can be measured the line, also point under various working conditions and easy to implement real-time online monitoring and early warning.
• Optical fiber is itself for sensor in densely inhabited areas, fire and explosion, corrosion resistance,resistance, high voltage and strong electromagnetic field, resistant to radiation, essential safety;
• Anti-jamming performance is strong, no breakdown, burned.
• The laying of the optical fiber cable or only, no electronic equipment, the system reliability.
• According to need to be set up, adjust too hot or too cold alarm threshold.
• Monitor the visual display measured parts of the specific location and name, real-time continuous temperature monitoring.
• The system can be monitored for each area and monitoring stations fault trend of intelligent analysis, and accurate positioning.
• Save and may at any time inquires the historical data, be helpful for the accumulation of experience and for fault trend analysis provides the basis.
• System has a local area network interface, links to enterprise local area network system or other network system, the realization information sharing.
• System has since diagnosis function, can be instantaneous optical fiber cable fault or judge.
• Advanced technology, application field widely.
