Special features of the RS-422 interface:

  • Up to 24 sensors with different tension ranges and designs may be connected in one line (data transfer max. 200 readings/sec.)
  • Connection to RS-232 using a converter (RS-422 – RS-232).
  • The RS-422 signal can be used for a single sensor over a distance of 1000 m.
  • Each sensor can individually be addressed and set up
  • Can be connected to PLC controls with digital input
  • Simple connection to BUS-Systems using gateways

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

Determining the force for 1 roller tension sensors

The tension range can be calculated for every wrapping angle with this formula:

Formular to determine the force of single roller tension senorsWhen 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.
