- Description
- Technical Data
- Various mounting options such as flange bearings, pedestal bearings, inner/outer fastening enable position-independent installation
- Highly reliable in operation thanks to overload protection up to 20 times the nominal measuring force
- Different shaft diameters from 12 to 65 mm and nominal measuring forces from 0.05 to 10 kN ensure a high degree of flexibility
- For measurements in a horizontal direction, the weight of the roller does not affect the measured result
- Good thermal behavior and high degree of linearity of the measuring elements due to strain gauge application on a flat surface
- High permissible operating speed of the measuring roller due to high web load cell spring constant
- Best surface protection due to chemical nickel plating
