Radial force measuring axle RFS® 100
On-line tension measurement up to 100 N resulting force
 •  designed as a single-roller system -
   uses an existing reversing point for tension measurement
•  very small size
  robust and easy to adapt
  independent of the force introduction point / lever arm
  available in 11 rated load ranges:
    0 to 2N   ... 0 to 5N        LR - Low Range
    0 to 10N ... 0 to 60N      SR - Standard Range
    0 to 100N                      HR - High Range

Description
RFS® stands for enduring online precision. The specified and calibrated accuracy remains unchanged throughout the unit’s service life and, across wide ranges, is independent of
  the force introduction point, i.e. the sensor is not affected by lever arm action
  any axial tilt torques which might appear
  direct axial forces
The functional principle makes for superb sensitivity while at the same time offering enormous performance capabilities. The force acting radially at the bearing journal, along the measurement vector, causes a microscopically small, elastic deformation of the complex load cell. This deformation is registered at an exactly pre-determined position by way of strain gauges and is then evaluated electronically.
The high mechanical stiffness of the load cell enables measurement with virtually no excursion.
This tension measurement principle is based on the evaluation of the force applied radially and transferred to the sensor by way of the bearing journal. This force is determined by the reversing geometry and the line tension.

Special features
  extremely compact and small design - for 16mm mounting hole
  existing reversing points can be adapted as measurement points
  overload protection up to 800%
  independent of the force introduction point, i.e. the sensor is not affected by lever arm action
  no influence of any axial tilt torques or direct axial forces which might appear
  centrifugal force will take no affect with optimal alignment in rotating purposes
  robust, stainless steel housing
  thought-through concept of housing for simple mounting
  suitable to design small measuring rollers
