CUSP-M

The CUSP-M multi-channel seismic datalogger is a multi-channel UTC-synced structural health monitoring and dense-array data capture system
 
Based on the operating system and application suite of the CUSP-3 series, the CUSP-M offers synchronised sampling of 96 24-bit channels (currently configured as 32 X 24-bit or 32 X 16-bit 3-channel sensors) making it ideal for dense arrays or structural monitoring. The use of robust LVDS communications to the sensors and remote signal digitisation allows sensor-to-processor cable runs of up to 400m. Standard Ethernet wire is utilised, resulting in extremely low-cost wiring and many structures can be instrumented using the pre-existing Ethernet network, decreasing both the installation cost and time and minimising the disruption to the buildings inhabitants.

The use of UTC synchronised sampling with large ring buffers allows multiple CUSP-M units to be operated in parallel. The availability of differing signal converters allows the use of end-user provided sensors and adaptation to diverse applications quickly and cost effectively. Current sensor options include 17-bit and 13-bit strong motion accelerometers, LVDT displacement sensors, wind sensors and bore-hole accelerometers. Geophone interfaces are also avaliable.

Basic specifications:

  • 8, 16, 24 or 32 times 3-channel 24-bit or 16-bit sensors per unit (up to 96 x 24bit channels)
  • 50, 100 or 200Hz sample rate
  • UTC synchronised sampling
  • Multiple central units with synchronised sampling - can synchronise/configure devices over Internet
  • Utilises LVDS signalling for long sensor to central processor distances (up to 400m)
  • Same rugged, clear, intuitive and powerful Internet interface style as CUSP-3 series
  • Optional adapters available for monitoring other parameters or sensors or for customised applications
  • SEEDlink streaming data output
