Product overview
The Wuxi Beiwei Sensing Technology BW-MINS325E provides inertial attitude measurement for integration into unmanned aircraft and other mobile or stabilized systems. Its CAN interface supports connection to a host system, with a maximum output frequency of 500Hz. Attitude specifications distinguish 0.3° dynamic accuracy from 0.01° static accuracy, while the measurement envelope covers pitch through ±90° and roll through ±180°. Heading retention is specified separately at 0.1°/60s, giving integrators a time-based heading parameter alongside the attitude measurements.
Physical integration options comprise a packaged unit measuring 97 × 63 × 27.2 mm and a bare-board format measuring 60 × 54 × 6 mm. The bare board’s length and width may vary by ±1mm, so installation space must accommodate that qualification. Weight is 280g including the cable. This is an inertial navigation component for incorporation into a larger system; its described configurations are the packaged sensor and bare board, rather than a flight platform or airframe kit.
Electrical integration requires a 9-36V DC supply, with operating current of 30mA and a 40mA maximum. Temperature compensation accompanies an operating range of -40 to 85°C; storage extends from -55 to 100°C. Environmental specifications include electromagnetic compatibility in accordance with GBT17626, insulation resistance of at least 100 MΩ, and shock resistance of 2000g for 0.5ms, applied three times per axis. The mean time between failures is specified as at least 90,000 hours.
