Applications

• Earthquake/seismic recording instrumentation
• Seismic data for high-rise/tall buildings and dams
• Strong-motion networks for large structures
• Accelerometer sensor arrays for earthquake shake monitoring
• Instrumentation for compliancy with seismic/earthquake building codes

Features

• Automatic triggering and recording of all earthquakes of interest
• Tri-axial MicroSMA accelerometer with self-test
• System of three NetDASunits (top, mid and lower levels)
• Remote maintenance and access via the Internet - reduced visitation costs
• Common time base and common triggering
• Wide dynamic range
• Standard Cat-5 cabling – no special cabling
• Directly interface to the Local Area Network (LAN)
• Avoids “red-tagging” after large earthquakes
• No hidden communication hardware or other costs
• Automatic earthquake notification via the Internet
• 36-hour run time without power
• LED earthquake/event status lights
• RS485 time synchronization
• Multi-GB recording capacity to Flash memory
• Optional central computer/base station for local real-time access
• Off-the-shelf availability

CRONOS Strong-Motion System
The Cronos system consists of two or more NetDAS accelerographs interconnected via the building’s Local Area Network (LAN) and/or Cat-5 cable. By employing the LAN and Cat-5 cable greater flexibility and lower cost is achieved. The master NetDAS recorder synchronizes the time of all other units. Common triggering is achieved via the LAN. Each NetDAS recorder communicates with the other recorders as well as off-site computers for remote servicing. Remote servicing saves considerable time and expense as opposed to on-site servicing.
