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.
