Product overview
The BWSENSING BW-IMU630 is an inertial measurement unit for navigation, attitude measurement and platform stabilization, with applications including unmanned aircraft and underwater robots. Its sensing architecture includes a gyroscope and accelerometer, with orthogonal compensation and RS422 output. The unit measures 44.8 mm long, 38.6 mm wide and 19.0 mm high, providing a compact physical envelope for integration. Other applications include pipeline measurement engineering, model attitude-angle measurement and autonomous-driving navigation platforms.
The gyroscope range is ±400 deg/s, and the featured accelerometer range is ±20g, with ±10 g, ±20 g and ±40 g selectable options. Temperature compensation accompanies a -40°C to +85°C temperature range. Gyroscope stability is ≤15 deg/h at normal temperature with 10 s smoothing; accelerometer bias stability is ≤0.1 mg with 10 s smoothing. The system specifications also include 2000 g shock resistance and 20 grms vibration, alongside angular and velocity random-walk limits.
