Product Description
Hello. If you are reading this, you are likely planning a seismic survey and wondering which components will give you the best chance of success. You are in the right place. Choosing the right Seismic Cable is one of the most important decisions you will make. It is the direct link between the ground vibration and your recorded data. A poor-quality Geophone Cable introduces noise and uncertainty, while a high-quality Geophysical Cable delivers clean, reliable signals that make processing and interpretation a breeze. Our goal is to help you select the perfect configuration for your specific project, whether it is a shallow engineering study or a deep crustal investigation.
To do that, we offer a full spectrum of channel counts. For small-scale refraction or MASW surveys, our 3, 6, or 12 Channels Cable is compact and efficient. For standard engineering projects, our 24 Channels Cable is the workhorse. And for high-resolution reflection or large 3D arrays, you need the density of our 48 Channels Cable. The cable itself has a durable 7.2mm OD jacket, protecting the internal cores without being overly stiff. We include high-quality NK-27K or 24-61 (Optional) connectors because we know a bad connection ruins a whole line. The geophone takeouts are available in two main styles based on your field preference: the Muller Take-out Molded Type for maximum durability in rough terrain, or the Split Spring Take-out Ordinary Type for crews that prefer to do their own field repairs.
We also understand that no two surveys are laid out the same. That is why we offer complete customization of the Lead-in Length and Interval Distance. Need 7.5 meters between geophones? No problem. Need a 25-meter lead-in to keep the seismograph out of the dust? We can do that. And we guarantee that whatever configuration we build will operate flawlessly in your local climate, thanks to a robust -40ºC to +70ºC working temperature range.
Think of us as your one-stop shop for geophysical success. Beyond cables, we manufacture a comprehensive range of equipment including Resistivity Meters, IP instruments, Electrical Resistivity Tomographs, Magnetometers, Borehole Cameras, and Well Logging systems. This breadth of knowledge means we can advise you on the entire workflow. Our company is structured around you, with a dedicated professional management team, a creative technology research, development & design team, and a responsive sales and after-sale service team. We provide strong service support from the first inquiry to the last data point. We will provide according to your actual requirements, the most suitable equipment and technical proposal, as well as complete training and guidance on installation, debugging, and maintenance.
Why Our System is Right for Your Project
Let's look at how our technology directly benefits your project outcomes. Our focus on High-Resolution Seismic Exploration means you get superior data, even in challenging environments. The secret is the independent 32-bit high-precision A/D converter on every channel. This allows for ultra-high sampling rates up to 250 kHz, capturing sharp interfaces. The extremely low background noise (≤ 0.15 μV) is crucial for seeing subtle reflections, and the exceptionally wide dynamic range (>140 dB) ensures you don't lose data from strong or weak sources. This is all about ensuring precise capture of faint signals so your interpretation is based on geology, not system noise.
If you work in urban areas or environmentally sensitive zones, you will love our Natural Source Surface Wave Exploration capability. It uniquely allows you to use ambient noise (microtremors) as your source. This requires no artificial seismic sources, so you avoid the costs and regulations associated with hammers, weight drops, or explosives. It provides safety, efficiency, zero disturbance, and zero pollution. The system rapidly inverts shear wave velocity profiles (Vs(z)) for precise stratigraphic delineation from depths of several metres to hundreds of metres. It is the ideal solution for urban shallow structure surveys.
For large-scale projects, our systems can collaborate using Multi-Unit Collaborative Operations. They connect via wireless ad-hoc networking technology, allowing you to monitor a huge spread from a single point. Clock synchronisation is taken care of with GPS high-precision timing (≤ 1 μs) for surface work, or OCXO time-keeping (long-term drift < 0.1 ppm) for long-term passive monitoring. This flexibility enables construction of large arrays, long lines, and distributed observation systems.
And we take the guesswork out of triggering. Our Intelligent Triggering System adapts to your source. Use a physical trigger for a sledgehammer, a time trigger for precise scheduling, or let the system auto-trigger with threshold or STA/LTA algorithms. This ensures comprehensive synchronisation, integrity, and automation, so you can be confident your data set is complete every time you roll up the cable.
