TitanSMA
Summary
The TitanSMA is a strong motion accelerograph specifically designed for high-precision observational and structural engineering applications and research requiring exceptional dynamic range over a wide frequency band.
The TitanSMA features the Class “A” Titan triaxial force balance sensor, with its low noise floor, exceptionally low hysteresis and industry-leading dynamic range. The integrated digitizer and recorder facilitate both standalone and networked free-field monitoring deployments.
Users get seamless access to events and recorder data (PGA, PGV, PGD, Sa) as well as instrument configurations and control for each TitanSMA and all TitanSMAs within a network with any web-enabled device via the events page resident within the GUI of each individual accelerograph.
Data is readily available via streaming to a central server or retrieved on demand from a central site. For non-networked instruments, data is easily retrieved via removable SD card, or downloaded onto an external USB drive on demand, in MiniSEED or ASCII formats.
The TitanSMA is ideal for civil defense applications with its ultra-low latency (down to .25 seconds), real-time processing and transmission events and network integration capabilities for event triggers and voting.
Nanometrics’ TitanSMA might be right for you if:
- You require the highest quality data sets
- You’re looking for exceptional dynamic range over a wide frequency band
- You want easy access to events, recorder data and instrument configurations and control via a web browser
- You’re carrying out civil defense applications, like early warning systems or shake maps
