Optical Sensing — Huawei OptiXsense
Huawei OptiXsense EF3000-A50 Distributed Fiber Optic Sensor
Huawei OptiXsense EF3000-A50 is mainly used to inspect buried pipelines. When there are mechanical or manual excavations nearby or above a pipeline, a monitoring optical fiber is deployed above the pipeline to sense vibrations and transmit vibration waves to the fiber sensing device. In the case of an unexpected event, the device quickly analyzes the vibration waveform information, identifies the event type, accurately pinpoints its location, and then reports the alarm accordingly. This inspection process facilitates online, real-time monitoring and safety warning of the entire pipeline, as well as providing a solution purpose-designed for the unmanned inspection of pipelines.
