Cronos Large Structure Seismic Recording System
Cronos Seismic Recording System

Cronos consists of several NetDAS accelerographs interconnected via the building’s Local Area Network (LAN) to record large earthquakes. Cronos is building code compliant and satisfies the requirement for seismic recorders. By employing a LAN (as opposed to costly analog cables) greater flexibility in communications, access and maintenance is achieved. The Master NetDAS serves time (CMOS clock or GPS) to all other units. When the LAN is connected to an Internet router Cronos can be maintained and earthquake data retrieved without site visitations resulting in cost savings over older technology requiring periodic visits.
