MicroStrain by HBK 3DM-MV7-AR Gyro-Stabilized Inclinometer (IMU)

Microstrain by HBK 3DM-MV7-AR Gyro-Stabilized Inclinometer (IMU) delivers precision measurements of dynamic inclination, angular rate, and acceleration in challenging environments, such as those encountered by heavy-duty construction, off-highway, agricultural, and trucking vehicles. The 3DM-MV7-AR utilizes the power of a sophisticated auto-adaptive Extended Kalman Filter (EKF) to remove errors associated with vibration, sudden linear motions, and quake, resulting in a true reading of inclination under all conditions.

The Microstrain by HBK 3DM-MV7-AR features state-of-the-art temperature compensation and calibration, ensuring error-free performance over the full operational temperature range. The compact size, wide 4.5VDC to 36VDC power range, IP68/IP69K rating, and SAE J1939 communications protocol make the 3DM-MV7-AR a single-part solution for a full range of vehicle sizes and applications.
