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 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 predetermined 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.
