Reftek Bronco - Model 151D - Broadband Seismometer - Brochure

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.
