Product overview
The Wuxi Beiwei Sensing Technology BW-VG325E is a CAN bus inclination sensor for measuring pitch and roll in moving or stationary equipment. Its applications include unmanned aircraft, robots, platform stabilization and vehicle machinery. Gyroscope drift compensation, a dedicated bias-tracking algorithm and Kalman filtering support its attitude measurements. Dynamic accuracy is 0.3°, while static accuracy and resolution are each 0.01°. Its measurement envelope extends to ±90° in pitch and ±180° in roll.
Mechanical integration has two dimensional references: a packaged sensor measuring 97 × 63 × 27.2 mm and a bare board measuring 60 × 54 × 6 mm. Bare-board length and width may vary by ±1 mm. Weight is 400 g including the cable, or 480 g including packaging. Electrical integration requires 9–36 VDC and a CAN connection, with a maximum output frequency of 500 Hz. Operating temperature spans −40 to 85°C; storage temperature spans −55 to 100°C.
