Product overview
The Wuxi Beiwei Sensing Technology BW-IMU630 is a high-performance inertial measurement unit with gyroscope and accelerometer sensing. Its applications include unmanned aircraft, pipeline surveying, model attitude-angle measurement, platform stabilization, autonomous-driving navigation platforms and underwater robot navigation. The unit measures 44.8 mm long, 38.6 mm wide and 19.0 mm high, defining its physical envelope for integration. It provides RS422 output and incorporates orthogonality compensation. Temperature compensation accompanies a temperature range of -40°C to +85°C.
The gyroscope has a ±400 deg/s measurement range, stability of ≤15 deg/h at normal temperature with 10 s smoothing, and angular random walk of ≤0.2 deg/h^0.5. The featured accelerometer range is ±20g, with ±10 g, ±20 g and ±40 g selectable options. Accelerometer bias stability is ≤0.1 mg with 10 s smoothing; velocity random walk is ≤0.01 m/s/s^0.5 and bias instability is ≤0.01 m/s^2. System specifications include 2000 g shock resistance and 20 grms vibration.
