Product overview
The BWSENSING BW-VG325E is a CAN bus inclination sensor with dynamic and static measurement capabilities. Its applications include unmanned aircraft, platform stabilization, robotics, autonomous driving, underwater ROV navigation, special-purpose vehicles, construction machinery and agricultural machinery. Sensor processing includes gyroscope drift compensation, a special bias-tracking algorithm for drift elimination and Kalman filtering. The inclination range covers pitch of ±90° and roll of ±180°. Dynamic accuracy is 0.3°, static accuracy is 0.01°, and resolution is 0.01°.
The packaged sensor measures 97 × 63 × 27.2 mm, while the bare board measures 60 × 54 × 6 mm; bare-board length and width may vary by ±1 mm, with actual dimensions governing. Weight is 400g including cable and 480g including packaging. The sensor uses a 9–36VDC supply, draws 30mA with a 60mA maximum, and communicates over CAN at baud rates from 25k to 500k. Maximum output frequency is 500Hz, and startup delay is below 50ms.
Operating temperature extends from −40 to 85°C, and storage temperature from −55 to 100°C. Shock resistance is 2000g for 0.5ms, with three shocks per axis. The BW-VG325E has high-level EMC protection, electromagnetic compatibility according to GBT17626, and insulation resistance of at least 100 MΩ. Mean time between failures is at least 90,000 hours. These electrical and environmental specifications accompany its dynamic and static inclination measurement functions and CAN bus output.
