Model 44000 Seismometer System Development
Abstract
The purpose of the project was to develop a new borehole seismometer system that has a lower life-cycle cost, but has performance characteristics that are equal to or better than the Teledyne Goetech Model KS36000 Seismometer System. Since the cost of the borehole is a major part of the installed cost of the Model KS36000 system, the approach recommended for the Model 44000 system was to incorporate designs that would make it possible to reduce the cost of boreholes by relaxing the borehole verticality constraints from 5 degrees to 15 degrees and reducing the required borehole diameter from not less than seven inches to not less than four inches. A second objective of the program was to provide design improvements that would overcome deficiencies that were known to exist in the Model KS36000 system. These included more rugged mass suspensions to reduce the possibility of damage caused by rough handling and force feedback through the center of mass to eliminate electromechanical resonances in the suspensions.
