AL – Aluminum force measuring bearing

  • Measuring body from high strength aluminum
  • Flexible installation concept
  • Accuracy class ±0.5%
  • For a wide range of applications

The Force Sensors of the AL-Series, designed for the measurement of tension on continuous material processing lines, include the bearing seat for life shaft rolls. This feature minimizes the space required at installation. The flexible installation options, including the standard 4-hole pitch circle and the optional 3-hole pitch circles, will allow for the straightforward replacement of existing flange style force sensors of other brands. With the superior performance of the AL-Series, accurate tension readings are obtained even with low web wrap angles and high roll weights.
