MOUNTING

Tension sensor FSR can be easily mounted everywhere a deviating point respectively a guide roller is built in at the machine. These places can be used as measuring point, assumed the in and outgoing angle is constant.

DETERMINING THE TENSION RANGE

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.
