Product overview
The Wuxi Beiwei Sensing Technology IMU425C is a packaged inertial measurement unit combining gyroscope and accelerometer measurement functions with CAN output. Its applications include unmanned aircraft, unmanned vessels, underwater robots, platform stabilization and industrial vehicles. The enclosure measures 60 mm long, 59 mm wide and 29 mm high, defining the physical space occupied by the unit. Its configuration includes dynamic compensation, orthogonality compensation and temperature compensation, with sampling at up to 500 Hz.
The gyroscope measures angular rates within ±400°/sec, while the accelerometer covers ±3.6 g on each of the X, Y and Z axes. The temperature range extends from -40 °C to +85 °C. Bias stability depends on the stated temperature and measurement interval: gyroscope room-temperature limits differ between 100-second and 10-second intervals, and the full-temperature limit is specified separately. Accelerometer bias stability is specified at 25 °C, also with separate 100-second and 10-second values.
