A new inclinometer from Hottinger Brüel & Kjær (HBK) aims to advance the safety, stability, and performance of vehicles and equipment in sectors like heavy construction, off-highway mining and agriculture and farming.
The MV7-AR is a 6 DOF gyro-stabilized inclinometer that delivers precise measurements of dynamic inclination, acceleration and angular rate — even in challenging environments.
Using a Auto-Adaptive Extended Kalman Filter (EKF), the MV7-AR removes errors that are usually associated with vibration, sudden linear motions and quake.
This 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.
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 degrees RMS at temperatures ranging from –40 degrees Celsius to +85 degrees Celsius.
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 1m
- Subjected to 50g shocks or rigorous vibration
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 grams 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.
The MV7-AR delivers performance in applications such as:
- Heavy construction — Used for platform levelling, boom/bucket angle control, auto-grading and operator safety.
- Agriculture and farming — Used for auto-steer, implement control, terrain following and field navigation.
- Mining and off-highway vehicles — Used for load monitoring, stability analysis and predictive maintenance.
