REF TEK strong motion products combine the third generation broadband seismic recorder (REF TEK 130-01) and an advanced low-noise force-balance accelerometer housed in an anodized aluminum instrument case with single point mounting and 3-point leveling.

The 130-SMHR is designed specifically to meet the USGS advanced national seismic system (ANSS) specifications for strong motion reference stations for deployment in urban areas and is supplied with an internal high resolution force-balance accelerometer, model 147-01. 

The mission of ANSS is to provide accurate and timely data and information products for seismic events, including their effects on buildings and structures and employing modern monitoring methods and technologies. The four main goals of the anss system are to establish and maintain an advanced infrastructure for seismic monitoring throughout the united states; continuously monitor earthquakes and other seismic events; thoroughly measure strong earthquake shaking at ground sites, in buildings and critical structures; and automatically broadcast information when a significant earthquake occurs for immediate assessment of its impact.

The 130-SMHR advanced communications features include TCP/IP over ethernet and asynchronous serial. Setup and control is accomplished with either a Palm-OS device running PFC_130 or a desktop computer running the RTI software package. An LCD continuously displays state-of-health and status information. The 130-SMHR includes an optional internal v.90 modem for connection via a public telphone network. The 130-SMHR also has a built-in battery charger for an external or optional internal lead-acid battery. The size of the 130-SMHR case allows the installation of an internal battery to provide backup power for more than 48 hours. The command/control interface allows the user to program and examine the instrument’s operating parameters and perform important diagnostic functions.

The 130-SMA is identical to the 130-SMHR with two exceptions: it has an internal mems 4G accelerometer with a dynamic range of more than 112 db, and the 130-SMA has a different oscillator for internal time keeping.

The 130-SMA is designed for building monitoring and is programmed with our special command line firmware interface, which allows for additional features such as 3 independent relay closure contacts for external alarm notification. The relay closure parameters are user selectable. The alarm relays can be activated in the 130-SMHR upon customer request. Contact the factory for more information.
