Product overview
The Wuxi Beiwei Sensing Technology FDVG527E is a high-precision dynamic inclination sensor with RS485 Modbus RTU communication. Its applications include UAVs, electro-optical pods, platform stabilization, unmanned underwater vessels, large ships, autonomous driving, special-purpose vehicles and wind turbine tower sway monitoring. Measurement processing combines Kalman filtering, nonlinearity and orthogonality compensation, and a special bias-tracking algorithm for drift elimination. The sensor covers pitch ±90° and roll ±180°, with static accuracy of 0.01°, dynamic accuracy of 0.02-0.05° and resolution of 0.01°.
The packaged sensor measures 97 × 63 × 27.2 mm, with a weight of 400g including cable and 480g including packaging. Bare-board dimensions are 60 × 54 × 6 mm; length and width may vary by ±1mm, and actual product dimensions take precedence. Electrical integration requires 9-36V DC, with operating current of 30mA and a 40mA maximum. Serial communication supports 2400 to 115200 baud, maximum output frequency is 100Hz, and startup delay is below 50ms. Operating temperature spans -40 to 85°C; storage temperature spans -55 to 100°C.
