The patented DynaTension® portable tensiometer measures tension in cable, rope, belt, optical fiber - virtually any material that is subjected to load.

DynaTension® meters compute the corresponding tension more accurately than conventional load cells, piezo- electric devices or dynamometer spring deflection methods.

This meter operates by sensing the fundamental frequency of vibration between two fixed points.

  • ±1% accuracy
  • Easy to use
  • Field proven
  • Reliable
  • Maintenance free
  • Patented

DynaTension meters are user friendly

It doesn’t come any easier than this!

  • Enter the weight per foot of the material to be measured on the key pad.
  • Enter the length in inches between your selected fixed points.
  • Position sensor parallel and near the cable. With other hand, tap cable.
  • DynaTension meter will show an accurate tension reading in seconds.

DynaTension® meters eliminate need for in-line installation, which allows normal operations to continue uninterrupted.

Our meter is simple to use, operating on a single rechargeable battery up to15 hours.

DynaTension® meters are proven worldwide, onshore and offshore. The durability opens up potential applications to include subsea, subsurface, air, and even the cosmos.

Today, the U.S. Navy’s entire fleet of aircraft carriers relies on DynaTension® meters to set critical tensions in aircraft elevators cables.

  • The computed tension is displayed on a large high contrast LCD in kilopounds (KIPS) or kilonewtons (KNS).
  • Measurements are given for tension in electromechanical, steel or synthetic cables without bends or sheaves for moving or stationary cable, chain, rope, belt, filament or webbing without physical contact.
  • Tension in stressed rods and beams can be accurately measured, too, over a range from less than .001 lb to 9,999,000 lbs.
  • DynaTension® meters operate maintenance free. There is no recalibration and operation is unaffected by weather, cable lubricants, dirt, shock or overload.
