Product overview
The BWSENSING BW-IMU525C is a high-performance CAN inertial measurement unit with gyroscope and accelerometer sensing. Its packaged dimensions are 60 mm long, 59 mm wide and 29 mm high. The unit provides CAN output, sampling at up to 500 Hz, dynamic compensation and orthogonality compensation. Its intended applications include unmanned aircraft, unmanned vessels, underwater robots, construction machinery, platform stabilization, automated guided vehicles, heavy trucks, autonomous driving and robotics. The temperature range is -40 °C to +85 °C, with temperature compensation.
The gyroscope covers ±400°/sec with 0.01°/sec resolution. Its room-temperature bias stability is below 0.5 °/h at 100 s and below 5 °/h at 10 s, both at 1σ; across the full temperature range, the limit is below 20 °/h at 10 s, 1σ. The accelerometer covers ±3.6 g on X, Y and Z with 0.01 mg resolution. At 25 °C, its bias stability is 0.001 mg at 100 s and 0.01 mg at 10 s, both at 1σ.
