Reftek Systems Inc. products

REF TEK’s latest generation broadband seismic recorder has a 32-bit A/D performance boost and a large dynamic range.  This enhanced dynamic range enables the Wrangler to record very small vibrations from seismic sensors, providing detailed data for scientific analysis. Available with 3 or 6 input channels, the Wrangler is a universal seismic recorder that works with most seismic sensors available today.

24-bit Strong Motion Accelerograph. 130-SMHR Strong Motion High Resolution Recorder provides accurate data and related information about seismic events, especially as they relate to 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. It is also certified under the California Strong Motion Instrumentation Program (CSMIP) and Los Angeles Department of Building & Safety (LADBS) Accelerograph program.

The SMHR2 combines Reftek`s latest generation of universal broadband seismic recorder, with the advanced high resolution, force-balance accelerometer, model 147. Designed to facilitate installation, security and maintenance in a single, secure enclosure optimized for early warning system installations.

The SMA2 combines Reftek`s latest generation of universal broadband seismic recorders, with the advanced high-resolution, capacitive accelerometer, model 131D. Designed to facilitate installation, security and maintenance in a single, secure enclosure optimized for structural monitoring applications.

The 147A Low Noise Accelerometer uses a state of the art force balance feedback technique to improve performance characteristics over conventional accelerometers. It is +/-4g full scale and has excellent dynamic range. Make the most of the dynamic range available by combining it with a 24-bi digitizer such as the Wrangler and the 130-MC Recorder. The 147A High-Resolution Accelerometers are a force‑balance accelerometer that converts acceleration signals into voltage signals to measure various low frequency and ultra-low frequency motion. The 147A accelerometer is available in both triaxial and uniaxial packages.

The 151D Bronco Broadband Seismometer is an observatory grade force-balance feedback velocity sensor available with the frequency bandwidth of 0.0083 Hz (120 sec) - 50 Hz. The seismometer contains three independent symmetrical sensors arranged in an orthogonal Galperin configuration. The sensor signals are deconvolved to provide the traditional ZNE orthogonal seismometer output for low noise and large dynamic range measurements.

This flexible and portable broadband seismometer is ideal for portable deployments and rugged enough for long term deployment in local and regional networks.

The compact REF TEK® Colt-PH™ broadband seismometer provides high quality data for scientists conducting earth movement studies.

The REF TEK184-GNSS is a smart antenna capable of receiving signals from GPS, GLONASS, Galileo and Beidou satellite systems in the LI bands. The 184-GNSS acts as a time source for the REF TEK 180 family of seismic data acquisition systems. This includes the SHMR2 and the Wrangler. It provides time and position information along with a 1Hz PPS signal that allows a seismic recorder to quickly discipline its timing TCXO to within #10 usee of UTC.
