Product overview
The Wuxi Beiwei Sensing Technology IMU427C is a packaged inertial measurement component for applications including unmanned aircraft, platform stabilization, robotics and autonomous vehicles. Its sensing architecture comprises a gyroscope and an accelerometer with X, Y and Z measurement axes. The enclosure measures 60 mm long, 59 mm wide and 29 mm high, defining the space required for the packaged unit. Integration features include RS232, RS485 and TTL output interfaces, Modbus protocol support, and sampling at up to 500 Hz.
The IMU427C provides dynamic compensation, orthogonality compensation and temperature compensation across a specified range of -40 °C to +85 °C. Its gyroscope measures up to ±400°/sec, while the accelerometer range is ±3.6 g on each axis. Bias stability depends on the stated temperature and averaging interval: gyroscope figures distinguish room-temperature operation from the full temperature range, and accelerometer figures apply at 25 °C. These measurement conditions are material when comparing the unit’s specifications for a particular installation.
