Innovative Seismic Monitoring Solutions: Advanced Broadband Sensors
Modern seismology relies on high-precision, durable equipment to capture critical seismic data. Among the three primary seismometer categories-Broadband Sensors, Short-Period Sensors, and Long-Period Sensors-the GD-3C Nodal Seismometer stands out as a groundbreaking solution for geophysical exploration and earthquake monitoring. This device combines cutting-edge synchronization algorithms, ultra-low power consumption, and superior signal detection capabilities, making it indispensable for professionals in harsh environments.
Core Advantages of the GD-3C Nodal Seismometer
Unmatched Synchronization Precision:
The integrated GPS/BDS/GLONASS/GNSS timing system ensures ±10μs accuracy, far surpassing traditional models. By leveraging multi-constellation satellite reception, the device maintains <1ppm timing stability, even in remote or obstructed terrains. This feature is critical for large-scale seismic arrays requiring synchronized data across hundreds of nodes.
Revolutionary Power Efficiency:
Designed with ultra-low power architecture and wireless charging compatibility, the GD-3C eliminates frequent maintenance. Its long-lasting battery supports continuous operation in extreme conditions, reducing downtime and operational costs. No physical connectors further enhance reliability, preventing corrosion or damage in humid or dusty environments.
Enhanced Signal Sensitivity:
Utilizing 32-bit analog-to-digital conversion (ADC) and adjustable preamplifier gain (0-36dB), the seismometer achieves a total dynamic range of 150dB. This allows detection of microseismic vibrations as low as 0.14μV, ideal for identifying subtle geological shifts. The configurable anti-aliasing filters (minimum or maximum phase) and low-cut filter options (1Hz or DC removal) ensure noise-free data acquisition.
Application Scenarios
Oil & Gas Exploration: Deploy the GD-3C in high-density nodal surveys to map subsurface structures with 0.25ms sampling resolution.
Earthquake Early Warning Systems: Its real-time data transmission and high sensitivity enable rapid response to tectonic activity.
Academic Research: The 128GB expandable storage accommodates prolonged field studies, while wireless communication simplifies data retrieval.
