DAQlink 5 is the fifth generation of portable seismograph systems. It can be configured as a stand-alone monitoring system, a refraction system, or a distributed seismic reflection system.

The 30 channel DAQlink 5 features six Auxiliary Channels. These channels are divided into two sets: Three channels with gains matching the other data channels; And three attenuated channels suitable for use with vibrators and other high-output sources.

Standard Features:

Six Auxiliary Channels

Three Matching Data Channels

The first three auxiliary channels have gain settings matching that of the other 24 data channels. When using an impulsive source, these channels can be used to record data from signature geophones. And for downhole sources, they can be used to record an uphole geophone.

Three Attenuated Channels

The second set of three channels feature 12 dB of built-in attenuation, increasing the input voltage range from 5 volts peak-to-peak to 20 volts P2P. This attenuation will match the DAQlink’s maximum input voltage to most vibrator controllers.

30 Total Channels

Capture Vibrator Signals

Perfect for Land Streamers

With the DAQlink 5-30 in the Recording Van, data for the source can be recorded simultaneously and store with the streamer data.

For Impulsive Sources, a 3-component geophone can be mounted on the streamer. Data from this sensor is then available for further processing.

For Vibrators, the three attenuated channels record the pilot, baseplate, and reaction mass traces. The pilot trace is used to cross-correlate the geophone data for field QC and later then for processing.
