TF Optic Fiber Tension Sensor

Made in Germany6 Tension Ranges
0–100 g up to 0–5.00 Kg

Large 70 mm aluminum rollers minimize bending of material which might damage or break the fragile filament.

The outer rollers are mounted on a movable plate to minimize contact when measurements are not being made.

Tension ranges of 10Kg and higher are available without moveable outer rollers.

Built-in signal conditioning with ZERO and SPAN pots provide a high-level, analog output to minimize the chance for signal interference.


  • 70mm V-grooved rollers are rated for speeds up to 5000 m/min
  • Specify TE-CABLE-CC 5 ft. connecting cable (optional, longer lengths are available upon request)
  • Frequency response of 100 Hz
  • 0-1 V DC output, proportional to tension (0-10 V DC optional)
  • Precision strain gauge sensing insures highest accuracy
  • Optional rollers are available for a wide variety of material profiles
  • Surface mount electronics provide long-term reliability
