INNO fibre optic temperature sensors ,temperature monitoring systems.
The DAS host is the core signal acquisition and processing unit of the DAS system, which can realize the acquisition, processing, analysis and storage of vibration signals on optical fibers. The DAS host is powered by DC24V with an average power consumption of 10W. It is externally connected to a high-performance AI artificial intelligence industrial computer; With the advantage of high-speed weak signal processing technology, it can achieve scanning frequencies above 50kHz and measure sound and vibration signals up to a maximum frequency of 25kHz, achieving industry-leading technical indicators.
At present, it has been widely used in fields such as underground oil wells, long-distance oil and gas pipelines, overhead power lines, national defense line safety, gas pipeline excavation prevention, communication and power line protection. There have been numerous application cases both domestically and internationally, which have proven that DAS products have unparalleled advantages in certain application fields.
