Key Product Features

The SM5 Tension Meter is designed to measure the static tension of all belt types and materials (timing belts, flat belts, V-belts) regardless of the tension member material. The SM5 is more accurate and easier to use than force deflection or elongation method. Use it with the free SM5 Pretension Calculator is a companion app available on iOS.


• Measuring range: from 7 to 450 Hz
• Measurement tolerance: ±5 Hz• Weight: 148g
• Dimensions (LxWxH): 117 x 78 x 24mm
• Battery: 9Volts
• Conforms to EC standard
• Simple one-button operation
• Accurate measurement results for optimal belt performance and life
• Save production and downtime with quick readings
• Satisfy quality system requirements with traceable certifi cation

Correct pre-tension enhanced the belt drive by:

  • Increasing service life
  • Improving reliability
  • Minimizing bearing load
  • Advancing positioning accuracy
  • Reducing noise level

The peripheral force (force transmitted through the belt) must be known to determine a recommended pre-tension. These recommendations are general and offered as a starting point. Adjustments may be necessary as determined by system performance. Having the Free SM5 Pretension Calculator App can help. Get it today for iOS or Android
