Product overview
The Wuxi Beiwei Sensing Technology BW-IMU527C is an inertial measurement component for integration into unmanned aircraft, robots and other mobile equipment. Its sensing architecture combines a gyroscope with acceleration measurement on the X, Y and Z axes. The packaged unit occupies 60 × 59 × 29 mm, defining its physical integration envelope. Dynamic and orthogonality compensation accompany sampling frequencies up to 500 Hz, while the output options comprise RS232, RS485, TTL and Modbus.
The gyroscope measures angular rates within ±400°/sec at 0.01°/sec resolution, and the accelerometer covers ±3.6 g at 0.01 mg resolution. Temperature compensation accompanies a specified range of -40 °C to +85 °C. Bias stability depends on the stated temperature and measurement interval: gyroscope limits differ between room-temperature and full-temperature operation, while accelerometer figures apply at 25 °C. Alongside unmanned aircraft, intended applications include platform stabilization, unmanned vessels, underwater robots, construction machinery, automated guided vehicles, heavy trucks and autonomous driving.
