Frequently Asked Questions
What is the core advantage of distributed fiber optic temperature measurement technology compared to traditional point temperature measurement?
Traditional technology can only detect the temperature at specific points, while the E3 series can achieve full-range detection without blind spots through a single optical cable, with a sampling interval of only 0.4 meters, equivalent to placing tens of thousands of detection points on a line of several kilometers.
What is the positioning accuracy of the system for locating the origin of a fire?
Using the Optical Time Domain Reflectometry (OTDR) principle, the system can calculate the location of a hot spot in real-time, achieving a positioning accuracy of ±0.5 meters, ensuring the precise identification of the accident source in the early stages of a fire.
How does the system sense temperature changes based on the "Raman scattering" principle?
When a light pulse propagates through the optical fiber, it generates Raman scattering signals, the intensity of which varies linearly with temperature. By capturing these subtle signal fluctuations, the system reconstructs the temperature distribution curve along the entire length of the fiber using high-speed algorithms.
How stable is the system in electromagnetic interference environments like power cables?
Since the sensing medium is an optical fiber, it uses optical signals for sensing, offering intrinsic safety and immunity to electromagnetic interference. It is particularly suitable for extreme electromagnetic environments such as high-voltage cables and substations.
What complex alarm logic does the system support to address different fire hazard models?
The system supports Fixed Temperature Alarms (reaching a set temperature), Differential Temperature Alarms (excessive temperature difference from the environment), and Rate-of-Rise Alarms (temperature rise is too fast), allowing it to adapt to various types of fire development scenarios.
When the optical cable suffers mechanical damage, how does the system quickly troubleshoot the fault?
The system features a built-in optical cable quality assessment function. It can locate fiber attenuation points or break points with a single click, automatically assess the loss, and help maintenance personnel quickly identify the fault location for repair.
What is the performance of the E3 series in long-distance monitoring?
The maximum detection distance for a single channel can reach 16 kilometers. This makes the system highly cost-effective for deployment in long-distance scenarios such as highway tunnels and urban utility tunnels.
What convenience does the system's software architecture offer for multi-terminal access?
The system is developed based on a B/S architecture and does not require the installation of a dedicated client. Management personnel can monitor the temperature distribution along the entire line in real-time via a browser on a computer, tablet, or mobile phone.
