Hottinger Brüel & Kjær (HBK) has unveiled the MV7-AR, a 6-degree-of-freedom (DOF) gyro-stabilized inclinometer that 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 typically associated with vibration, sudden linear motions, and quakes. This accuracy gives operators peace of mind during high-vibration operations, allowing them to make timely, effective decisions to protect safety, productivity, and efficiency.

In addition to the Auto-Adaptive EKF, the MV7-AR uses state-of-the-art temperature compensation and calibration. As a result, the inclinometer offers an accuracy of 0.25° RMS across temperatures from –40°C to +85°C.

This accuracy is reinforced by the MV7-AR’s ruggedized construction. Fully sealed in an IP68/IP69K-rated casing, it delivers complete reliability, even when fully immersed in water, subjected to pressure washing, dropped from a height of 1 meter, and subjected to 50g shocks or rigorous vibration.

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

Streamlined Integration

The MV7-AR is designed for rapid and easy deployment, allowing it to deliver results quickly and with minimal disruption. At just 107 grams and 78.9 × 55.0 × 23.5 mm, the unit fits into compact footprints with ease, in any orientation. The inclinometer uses the industry-standard SAE J1939 communication protocol, and has a power range of 4.5-36 VDC, making it compatible with a range of vehicles and applications.

The MV7-AR is expected to advance the safety, stability, and performance of vehicles and equipment in critical sectors, with applications including:

  • Platform leveling, angle control, auto-grading, and operator safety.
  • Auto-steer, implement control, terrain following, and field navigation.
  • Load monitoring, stability analysis, and predictive maintenance.
