Details
The Force Balance Accelerometer (AFB) is a high-sensitivity, ultra-low noise (>165 dB), 0-200Hz accelerometer designed for use in microseismic and seismic networks, monumental buildings, and high-mass civil and industrial structures.
These sensors use low-noise electronics in combination with the force-balancing principle to make possible measurements in the low-frequency microG range.
