The Advantages of Autonomous Recording Nodes
The sophisticated Hybrid SLIM (HSLIM) enables our customers to convert their cabled system into a wireless recording system using the same Smart Geophone building blocks. HSLIMs provide power, control, and data gathering functions for the connected SMG strings. One Autonomous Recording Node (ARN) can now support as many as 72 digital sensors per radio/battery, so the number of radios/batteries in large-channel (10,000+) and especially ULTRA LARGE (100,000+) systems can be reduced significantly.
Line connectors located on either end of each HSLIM allow them to make traditional line connections to other HSLIM units. In this way, HSLIMs can be utilized as components in either conventional, fully-cabled configurations or in the “cable-free” configuration which uses SAMs to record the data. With the right equipment, a user of the S-Flex system could actually switch back and forth between cabled and cable-free configurations using the same basic components, all dependent on the needs of any given survey and location.
