Specifications subject to change without notice!
Tension sensor SFZ can be easily mounted everywhere a deviating point respectively a guide roller is built in at the machine. These places can be use as measuring point, assumed the in and outgoing angle is constant.
For mounting, the sensor can be clamped on each position of the cylinder. Alternative a mounting flange or a clamping block is available (see additional Options).
The tension range can be calculated for every wrapping angle with this formula:
When selecting the nominal measurement force it is necessary to take into account the weight of the guide roll and raise the nominal load respectively, particularly when working with small nominal forces.
