Distributional acoustic sensor system DAS
Sensors
Ovlink
Channels: 1/2; amplifiable Detection frequency: 0-100kHz Response band: 0.01Hz-50kHz; 50kHz@1km
The MS-DAS system is a distributed acoustic sensor product with world leaders. The product uses autonomously designed micro-structured fibres, which are continuously distributed backwards; optical time-resilient sensing techniques based on photo-connected detection; and capable of continuously recording acoustic signal transmissions and acoustic spatial distribution along long-range fibres. The system is minimally detectable in response to Quadaana; response bands cover subacoustic to ultrasound bands; distributive measurements that can be applied to seismic waves, microvibration and microresponses; and applications in areas such as resource exploration, seismic monitoring, pipe safety and perimeter security have great potential. The distributed acoustic sensor system has desktop-based DAS-2000 III and rack-based DAS2100-R product types. Microstructure disassembly enhancement; ultra-high-input noise-compatible detection technology; ultra-high sensitivity self-referenced phase decomposition; comot noise inhibition multi-area hybrid reuse; broadband detection integrated design; simple deployment installation
