- Description
- Technical Data
- Aluminum roller with fixed axle and two integrated load cells
- For straightforward installation between the side walls
- Highly reliable in operation thanks to overload protection up to 10 times the nominal measuring force
- Different roller diameters from 80 to 200 mm ensure maximum 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
- The high value of the web load cell spring constant permits a high maximum operating speed for the measuring roller
