Product Description
RanCheng Group designed and manufactured the RC-1C Seismic Sensor as a lightweight, fully integrated node-based acquisition unit for both active and passive seismic surveys.
It combines a high-sensitivity geophone (2Hz, 5Hz, or 10Hz) with advanced GPS/BDS timing, ultra-low-power operation, wireless charging, and wireless pulse communication.
The 5Hz version weighs only 560 g without the tail spike, making it easy to carry for long-distance field deployment.
Thanks to its connector-free housing, strong environmental resistance, and long-life battery, the RC-1C is suitable for unattended outdoor operation and can support automatic deployment and retrieval workflows.
It provides a practical, scalable, and cost-efficient solution for large, high-density 3D seismic exploration.

Our seismic sensor combines a wide-band geophone with low-noise 32-bit Σ-Δ ADC for clear, stable waveforms.
2. Cable-free, lightweight node design
The wireless, compact unit (5Hz version 560 g) allows flexible deployment, fast module replacement, and minimal downtime.
3. GPS/BDS timing & wireless charging
High-accuracy timing ensures long-term synchronization, while wireless charging and sealed housing reduce maintenance in harsh environments.
4. Cloud & remote-operation support
Integrated cloud access, deployment IDs, and smart storage tools enable remote monitoring and efficient data management.
5. Multi-format data output & source compatibility
Supports SEG-2, SEG-Y, SEG-D, SAC, Mini-SEED, and works with both active and natural seismic sources.
Advantages
Versatile seismic surveys
One seismic sensor handles oil, gas, coal, microtremor, and engineering tasks.
Fast, flexible field deployment
Cable-free design and lightweight modules reduce manpower and simplify setup in complex terrain.
Reliable, high-quality data
Low-noise ADC and GPS/BDS timing deliver stable and consistent seismic results.
Efficient operation and management
Wireless charging, replaceable modules, and cloud tools shorten turnaround and improve workflow.
Customer Benefits
The RC-1C seismic sensor delivers reliable data for oil, gas, coal, and engineering investigations, enabling faster field deployment with fewer personnel. Its connector-free, rugged design reduces maintenance, while long-duration operation supports microtremor and passive surveys. Stable timing accuracy ensures consistent results over extended periods, and cloud-based tools simplify data management, helping to reduce overall project costs for large-scale 3D surveys.
Application
RanCheng Group develops the RC-1C seismic sensor to meet the needs of a wide range of subsurface investigation projects. It is used in seismic hazard and site-safety evaluations in earthquake-prone regions, shallow geological surveys, and urban underground space detection. The sensor also supports geothermal exploration, coal goaf mapping, and resource investigations for oil, natural gas, coal, and non-ferrous metals.
Designed to support both active and passive seismic methods, the RC-1C seismic sensor is well-suited for microseismic monitoring, ambient-noise imaging, MASW surveys, and active-source surveys. This flexibility ensures reliable performance across diverse geological and engineering environments.
The RC-1C seismic sensor is widely adopted by university professors and research teams engaged in seismic research, including ambient noise tomography and microseismic studies, as well as by scientific research institutions conducting advanced geophysical investigations. In addition, it serves oil, gas, and coal companies performing seismic reflection, seismic refraction, seismic exploration, and other active-source seismic operations in resource development projects.
