High Resolution Seismic Recording System - Distributed DAQLink 3

Distributed DAQLink 3 - Distributed High Resolution Seismic Recording System

The Distributed DAQlink III is the combination of a standard DAQlink III with an "expansion bubble". This expansion bubble houses a high-speed networking subsystem for passing trigger signals and seismic data between units. The entire system is connected to a computer controls the seismograph and stores the acquired seismic data.

The distributed system can be interconnected through conventional geophone-style cables, or high-speed network-style cables, or else conventional Wi-Fi transceivers. Plus, all Distributed DAQlink III units can be utilized as standard seismographs if the need should arise.

Field Benefits

Cutting Edge Technology for Data Quality

• Ultra High-Speed 24bit ADC (48,000 samples/sec)

• High Resolution Clock

• Low Noise & Low Distortion Means Better Data

Designed to Produce and Protect Data

• Data Always Stored in Box - No Lost Data

• Offload Data While Recording – No Lost Production

• Better Data Handling for Superior Production

Versatile Operation

• Continuous Recording

• Trigger on Time, Data Event or Trigger Input

• Different Modes for Different Types of Projects

Multiple Operation Modes

• Operate as Stand-Alone Seismograph - Great for Small Crews

• Multiple Units Operating in Concert - Increases Crews Flexibility

Sturdy Aluminum Construction

• Rugged, Lightweight, "O" Ring Sealed to IP 67

• Threaded Holes for Mounting

• For Permanent Mounting, or Long-Term Deployment

Downhole Recording

• 24 Channel Units Ideal for Shallow Holes with 8 three-Component Geophone Sondes

• Use WiFi network to collect data from multiple wells

Earth Monitoring

• Low Power for Long-Term Use

• Use Cellular Modem for Remote Data Collection

Useful for Every Project

• Engineering Seismic

• Oil & Gas Exploration

• MicroSeismic Frac Monitoring

• Strong Motion Detection and Monitoring

A MegaDAQ consists of multiple DAQ3-24s connected via a network. This can be either a wired or wireless network. The network both controls the seismographs and collects the seismic data in real time.
