DAQlink 5-24

Overview

The DAQlink 5-24 is a high-resolution, 24-channel portable seismograph designed for active-source acquisition, passive monitoring, refraction surveys, and distributed seismic recording. It combines high-speed 24-bit ADC performance, compact size, low power operation, and flexible Ethernet networking.

DAQlink 5 is the fifth generation of portable seismograph systems. It can be configured as a stand-alone monitoring system, a refraction system, or as part of a distributed seismic reflection system. Vscope software provides acquisition control, data QC, and file storage.

Multiple DAQlink 5-24 units can be stacked or networked together for larger high-channel-count systems, making the system useful for small crews, downhole acquisition, marine seismic, and large distributed seismic projects.

Benefits

Use One System for Many Applications
  • DAQlink 5-24 can be used for active-source work, passive monitoring, refraction, reflection, downhole, and distributed seismic acquisition.
Build Larger Systems Easily
  • Stackable and networked operation allows crews to expand from a compact 24-channel system to larger high-channel-count systems.
Improve Data Quality
  • High dynamic range, low noise, wide bandwidth, and 24-bit acquisition help capture clean seismic data in demanding field conditions.
Simplify Field Operations
  • Ethernet control, Vscope software, built-in testing, and flexible storage options simplify setup, QC, and data management.
Support Remote Monitoring
  • Continuous recording, cellular data support, FTP access, and event detection make DAQlink 5 suitable for remote monitoring projects.
Work with Existing Source Electronics
  • DAQlink 5 is compatible with Force 3, Boom Box 3, RTM3, and Universal Encoder 3 source control equipment.
Reduce Power and Field Burden
  • Compact size, low power consumption, and rugged IP67 construction make the system easier to deploy in remote field environments.
