ROBO®QUAKE is an advanced earthquake monitoring and early warning system designed by mageba to protect critical infrastructure through real-time seismic data processing, structural health diagnostics, and automated alerting. Operating as the primary sensor within this platform, the RQ-FBA200 model is a high-accuracy triaxial force-balance (servo) accelerometer engineered specifically for low-frequency structural health monitoring, seismic activity tracking, and geotechnical studies. Unlike conventional accelerometers, the RQ-FBA200 utilizes a closed-loop feedback mechanism that applies an electromagnetic force to counteract the movement of an internal proof mass, keeping it stationary to deliver measurement accuracy directly proportional to structural acceleration. Featuring a wide dynamic range exceeding 155 dB, self-noise performance below the Accelerometer Low Noise Model (ALNM), a selectable output range from ±0.25 g to ±4 g (40 Vpp differential output), a frequency response of DC to 215 Hz, and an industrial operating temperature range of -30°C to +85°C, the RQ-FBA200 accurately detects micro-vibrations, long-term structural sways, and high-amplitude earthquake shocks without signal clipping.
