6-dimensional motion sensor

The 6DF series of inertial measurement units (IMU) by Honeywell (USA) are designed to provide motion, position, and navigational sensing from a durable single device over six degrees of freedom. This is achieved by using MEMS (micro-electromechanical system) technology to sense translational movement in three perpendicular axes (surge, heave, sway) and rotational movement about three perpendicular axes (roll, pitch, yaw). Because the movement and rotation along the three axes are independent of each other, such motion is said to have “six degrees of freedom”.

THE SENSOR SYSTEM MEASURES the motion of the equipment onto which it is attached and delivers the data to the equipment's control module via the CAN interface. The CAN interface complies with CANopen or J1939-71. "Our 6DF series' aluminum packaging, sealing, corrosion-resistance, and chemical compatibility provide industry-leading durability from harsh environments," said Ted Tomita from Honeywell Sensing and Control. "Additionally, we have integrated the IMU with the algorithms, calibration, and environmental testing required for effective operation, easing integration and reducing total cost for the end customer."

The IP67- or IP69K-rated devices are temperature-compensated. They are designed for use in tractors, harvesters, mining conveyors, robotics, shaker tables, and other mobile machinery. Stability is a critical feature for all types of vehicles in motion and for those able to move large loads. The IMU can be used to help provide traction on uneven surfaces, or vehicle stability when a load or boom arm is extended on the job. This is also beneficial for automatic steering control because it provides tipping information to the vehicle. The sensor system can also be used to prevent vehicle rollover. Whether it's a vehicle traveling over rugged terrain, or a front loader with a heavy load, the sensor data warn the operator when the vehicle is approaching an angle of tilt or inclination that could lead to a vehicle rollover. In agriculture machinery helps to ensure a flat, smooth roadway or field for road grading or planting purposes. It may also be used to optimize harvester blade levels to maximize crop yield in uneven fields.
