Convert an old Sercel 408 or 428 into a new Nodal System |
System Overview: The most successful data acquisition system of our industry was designed by Sercel, France. It is called the 428XL Land seismic acquisition system. Over 5,000,000 channels were delivered around the world. The two major building blocks of the field telemetry are the FDU-428 and the DSU3-428. The 428XL system is a conventional cable system, designed for large field projects, e.g. the spacing between the Field Digitizer Units (FDUs) is typically 55-75 meters, enabling it to connect to an analog string of 6 to 12 analog geophones. |
U-Node Seismograph |
SI decided to adopt our successful multichannel-based U-Node system for the Sercel 428XL telemetry and provide a node system using the 428XL system components, the DSU3 and the FDU. The only difference between the two versions of the U-Node system is the telemetry interface. All features developed for our SMG telemetry will be available for the 428XL telemetry users, including the option to return full precision data in real-time. |
