Necessidade:
Header height and cutting bar adjustment
Precise adjustment of the cutting bar position allows the combine harvester to adapt to different ground conditions and crop heights, maintaining a constant distance from the soil. Accurate control of this parameter is essential to optimize cutting quality, reduce product losses, and increase overall productivity.
Solução:
- Installed inside the hydraulic cylinder, with no external encumbrance
- Contactless magnetostrictive technology ensuring measurement stability and long operational life
- Designed to withstand shocks, vibrations, and agricultural contaminants
Necessidade:
Header tilt angle adjustment
The ability to adjust the header tilt allows the cutting angle to be optimized according to the type of crop and the operating conditions. Monitoring the tilt angle through angular position sensors enables precise and continuous control of the header attitude, ensuring better ground following and reduced grain loss.
Solução:
- Contactless Hall-effect technology, ensuring long operational life
- Resin-sealed housing for maximum protection against dust, moisture, and external agents
- High resistance to shocks, vibrations, and extreme temperatures (up to 125°C)
Necessidade:
Driving pedals and command levers position control
In combine harvesters, accurate monitoring of the angular position of control pedals and command levers allows the onboard electronics to correctly interpret the operator’s intent. This ensures smooth and precise machine handling, increases productivity, and reduces fuel consumption across all operating phases.
Solução:
- Contactless Hall-effect technology ensuring long operational life
- Available with single or redundant output, and with various electrical interfaces, both analog and digital
