FSR Online Tension Sensor

FSR Single Roller Tension Sensor
Click images to enlarge.
Fined-mounted tension sensor, single rollers system, for mounting at an existing location to create a fixed wrap angle of the material over the sensor rollers.

29.5mm diameter hardened steel v-grooved roller is standard. Optional rollers include a U-Grooved Roller with 5mm radius, 70mm diameter lightweight roller for optic fibers and similar fragile filaments as well as ribbon rollers for flat materials such as tapes/bands, tows, ribbon cable, rectangular wires and similar flat materials.

5 ranges are offered from 0-10N (1Kg) up to 0-200N (20 Kg), rated in resultant force (therefore wrap angle must be taken into account and resultant force calculated)

Features

  • Includes integrated amplifier with "zero" and "gain" adjustment pots
  • Standard output is 0-1V DC
  • Optional outputs include 0-10V DC, 4-20mA, USB, RS-232 and RS-422
  • Optional Wi-Fi cable free data transfer available requires use of battery pack for sensor
  • Sensor can be mounted using holed in sensor body or front plate of sensor
  • Features full bridge strain gauge sensing for highest accuracy
  • Requires 15-24V DC regulated power for sensor excitation
  • Optional Digital Tension Indicators are offered

Determining the Tension Range

Determining the Tension Range
The tension range can be calculated for every wrapping angle with this formula:

FN = Nominal load (Multiplier * FZ)
FZ = Line Tension
α = Wrapping angle at the guide roll

FN = 2 * FZ * sin( α/2 )

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.
