HBK’s MV7-AR Sets a New Standard for Ruggedised IMUs

A new inclinometer from Hottinger Brüel & Kjær (HBK) is expected to uniquely advance the safety, stability, and performance of vehicles and equipment in sectors like heavy construction, off-highway mining, and agriculture. 

The MV7-AR is a groundbreaking 6 DOF gyro-stabilised inclinometer which delivers precise measurements of dynamic inclination, acceleration, and angular rate – even in the most challenging environments.

Using a sophisticated Auto-Adaptive Extended Kalman Filter (EKF), the MV7-AR removes errors that are usually associated with vibration, sudden linear motions, and quake.
This outstanding accuracy gives engineers and drivers new peace of mind during high-vibration operations, allowing them to make timely, effective decisions to protect safety, productivity, and efficiency. 

Built for the toughest jobs in the toughest environments
In addition to the Auto-Adaptive EKF filter, the MV7-AR also uses state-of-the-art temperature compensation and calibration. As a result, the inclinometer offers accuracy of 0.25° RMS at temperatures ranging from –40°C to +85°C.

This accuracy is reinforced by the MV7-AR’s ruggedised construction. Fully sealed in an IP68/IP69K-rated casing, it delivers complete reliability, even when fully immersed in water or subjected to pressure washing.

This makes the MV7-AR ideal for use in the most challenging outdoor environments. Engineers and drivers can work through snow, ice, rain, heat, or excessive vibration – and still be certain that their inclinometer is delivering accurate data. 

The MV7-AR is also designed so that engineers can deploy it quickly and easily, so that it can deliver outstanding results rapidly and with minimal disruption. 

At just 107 g and 78.9×55.0×23.5 mm, the unit fits into compact footprints with ease, in any orientation.

It uses the industry-standard SAE J1939 communication protocol, and has a power range of 4.5-36 VDC, making it compatible with a huge range of vehicles and applications.

With the MV7-AR, HBK is empowering engineers worldwide to build smarter, safer, more reliable vehicles and equipment – no matter their environment.
