PMD BB313
The BB313 instruments are designed as extremely robust, versatile, compact, lightweight, broadband seismic sensors. Each of the three identical sensor elements in BB313 is equipped with an efficient electrodynamic force-balancing feedback. BB313 is a more compact, lighter version of our BB303 seismometer, the difference being in a slightly higher noise at longer periods.| Part No. | BB313 |

ROBUST COMPACT ECONOMICAL BROADBAND SEISMOMETERS BB313, BB313-OBS Unlike traditional seismometers, they are based on proprietary electrochemical technology 1 that provides many advantages over the conventional electromechanical sensors. The instruments are offered in two application-dependent versions. The standard BB313-(LN) is the reduced noise version. The BB313-SM has a higher clip level and is used for strong motion applications. Both versions have the same dynamic range, which is shifted up by approximately 10db in the ‘SM’ relatively to the standard ‘LN’ version. The BB313 instruments have been recently redesigned. Also available are a single component version BB313U, a very low power customized lightweight, compact ocean-bottom seismometer (OBS) BB313-OBS (photo on the right above), and a narrow (83mm diameter) borehole model BB313-BH The latest BB313 seismometer contains a microcontroller which maintains exceptionally accurate parameter stability over the full operating temperature range and over the life of the instrument.
