The FBA-3 is a 3-component accelerometer with a range of
perhaps 1/2 to 1 g acceleration. It was used in combination
with a digital data acquisition system to record vibrations
from strong earthquakes.  Typcially, systems would be
installed in the basement, roof, and middle of a building to
record the structural response to earthquakes. Variations
were used in boreholes to study ground spectral
amplification ratios and as parts of systems in other

The FBA-3 has no practical purpose in recording small or
distant earthquake.
