A-3500 Distributed Fiber Optic Temperature/Strain Sensing System (BOTDA)
Product introduction
The series of distributed fiber optic temperature/strain sensor (DTSS) can obtain the spectrum information of Brillouin backscattered light at any place of the sensing fiber, and demodulate the strain, temperature, and losses along the fiber simultaneously.
This product benefits from a single-terminal nondestructive monitoring structure, excellent accuracy, long dynamic range, and high repeatability. This device can be controlled remotely, and process data on a remote server, which makes it easy to integrate with third-party systems.
Features
High speed of the Brillouin spectrum peak detection, real-time signal processing by FPGA.
High precision and separate temperature/strain measurement, ensuring parallel sensing accuracy
Stable light pulse with ultra-high extinction ratio to improve the accuracy over a long distance
High sensitivity broadband microwave technology, reducing the complexity of the design and improve the stability
Powerful local database
Typical applications
Real-Time health monitoring and breakpoint localization of communication fiber optic cables (including submarine cables, communication fiber cables,etc.)
Monitoring geological disasters such as landslides and subsidence
Monitoring leakage of oil and gas, and heat monitoring in pipelines
