The 130 Strong Motion High Resolution Recorder combines the functionality of the 130S Broadband Seismic Recorder and an advanced low-noise, force-balance, triaxial accelerometer to deliver accurate data and information for seismic events, including their impact on buildings and structures.

The 130-SMHR meets the USGS Advanced National Seismic System (ANSS) specifications for strong motion reference stations for deployment in urban areas and has an internal high resolution force-balance accelerometer with a dynamic range >155dB, and a high precision oscillator for precise time-keeping. The time keeping accuracy is ±10 µsec with GPS locked and a validated 3-D fix.

The 130-SMHR advanced communication features include TC/IP over Ethernet and asynchronous serial. To setup and control the 130-SMHR you can use the iFSC Controller or a desktop computer running the RTI software. The 130-SMHR case allows the installation of an internal battery to provide backup power for more than 48 hours.

An LCD displays health and status information, and the command/control interface allows the users to program and examine the instrument’s operating parameters and perform important diagnostic functions, such as acquisition status, sensor calibration and trigger parameters.
