Description

Digital Array (DA): High-Performance Multi-Sensor Data Logger

The Digital Array (DA) is a compact, cost-effective, and portable real-time data logger (digitizer) designed for efficient multi-sensor data acquisition. It seamlessly integrates with mono-, bi-, and triaxial MEMS or force balance accelerometers (FBAs), tiltmeters, and seismometers via a high-speed digital bus, enabling precise synchronization and flexible sensor configurations.

Reliable Digital Architecture & Long-Distance Connectivity

Unlike traditional analog systems, the DA system uses fully digital sensors, transmitting data through a standard low-cost CAT-6 cable. This allows for long cable runs without signal attenuation, ensuring accurate and reliable data acquisition even at extended distances.

Scalable & Synchronized Data Streaming

A PC interface or SL06 recorder with GPS ensures accurate timing, data logging, and processing. Sensors are linked in a daisy-chain configuration, with each branch supporting up to 8 nodes. Multiple branches can be configured to stream data via TCP/IP and SeedLink protocols, providing seamless integration with widely used seismic and monitoring systems.

For example, a master recorder can manage:

• Two branches with 4 nodes each
• A single branch with 8 interconnected nodes

This modular approach allows flexible deployment across a range of monitoring applications.

Borehole Sensor Integration for Subsurface Monitoring

The DA system is also fully compatible with borehole sensors, enabling high-precision subsurface data acquisition. With its digital borehole sensor nodes featuring an automatic locking mechanism, users can easily configure vertical sensor arrays within a single borehole, ensuring optimal performance in geotechnical and seismic studies.

Cost-Effective & High-Performance Solution

One of the DA system’s greatest advantages is its cost-effectiveness, delivering high-end performance at a competitive price. Its digital architecture and long-distance CAT-6 connectivity guarantee synchronized, interference-free data transmission, making it an ideal choice for deep borehole installations and large-scale seismic networks.

The Digital Array (DA) system is a powerful, scalable, and affordable solution for advanced seismic monitoring, structural health analysis, and geophysical applications.
