DMU11 Inertial System

Low Cost 6 DOF Precision MEMS Inertial Measurement Unit

About the DMU11 Inertial System

DMU11 combines MEMS angular rate and linear acceleration sensors to create a precision, low-cost, six-degrees-of-freedom (6-DOF) IMU for complete motion sensing and control in three-dimensional space. However DMU11 features a redesigned layout to minimise physical space, for applications where space is at a premium. DMU11 is suitable for a wide range of applications and is calibrated over the full rated temperature range.
