Product overview
The Beiwei Sensing IMU400C is an inertial measurement unit for unmanned aircraft, robotics, autonomous driving and platform stabilization. Its packaged dimensions are 60 mm long, 59 mm wide and 29 mm high. Its sensing specifications cover a gyroscope and an accelerometer, with acceleration measurement across the X, Y and Z axes. Other intended applications include unmanned vessels, underwater robots, construction machinery, automated guided vehicles and heavy trucks. The product is an inertial sensing component for these systems.
The IMU400C offers selectable RS232, RS485 or TTL output and sampling up to 500 Hz, together with dynamic and orthogonality compensation. Temperature compensation accompanies a temperature range of -40 °C to +85 °C. The gyroscope measures up to ±400°/sec, while the accelerometer range is ±3.6 g on each axis. Gyroscope bias stability has separate room-temperature and full-temperature specifications. Accelerometer bias stability is specified at 25 °C, with separate values under the stated 100 s and 10 s conditions.
