Welcome To Seismic Source Company

Seismic Source Company is a manufacturer of seismic instruments and data acquisition systems. Its products are used in a broad range of applications: Seismology, Structural Monitoring, Seismic Site Evaluation, Civil Engineering, Gas and Oil Exploration, Industrial Vibration Monitoring.


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.


MegaDAQ: Multiple DAQ3-24s



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.
