AFB series

Product catalog summary

Overview: The AFB Force Balance Accelerometer is a high sensitivity sensor designed for long-term monitoring of structures such as dams and buildings, particularly for seismic events at low frequencies. It is self-contained, providing high-level, low impedance output without the need for signal conditioning in most applications.

Applications: The accelerometer is ideal for long-term monitoring of dams, buildings, and heritage structures, especially where higher sensitivity is required.

AFB - FORCE BAL A NCE ACCELEROMETER Accelerometer Force Balance AFB is a high sensitivity sensor for long-term monitoring of dams and buildings, ideal for studying seismic events at low frequencies of motion. Solgeo Models AFB Force Balance Accelerometers are high sensitivity, low noise sensors designed for use in seismic and low level, low frequency motion studies. The accelerometers are self-contained and provide a high level, low impedance output. No signal conditioning is required in most applications. These sensors utilize low noise electronics in conjunction with the force balance principle to make possible measurements in the low frequency micro-G range. Aside from the traditional DC-coupled zero output, the AFB-3C& 2C & 1C also provides AC coupled zero output which eliminates tilt induced or offset errors facilitating high amplification of the basic output. APPLICATIONS • Long-term monitoring on dams, buildings and heritage structures • Monitoring that requires higher sensitivity Solgeo - Via Pastrengo, 9 - 24068 Seriate (BG, Italy
