The new CHECK-LINE Model SK 122 FM Tension Sensor measures the running line tensions of wires, cables and similar process materials.

Its unique strain-gauge design delivers excellent measurement precision and stability as well as providing maximum overload protection.


  • 17mm non-rotating bearing journal
  • Designed as a single-roller system -uses an existing reversing point for tension measurement
  • System of protection IP67 - waterproof
  • Resolution of 0.1% and better
  • Rugged stainless steel housing is environmentally sealed
  • Threaded housing with lock-nuts permits easy mounting and simple alignment
  • Overload protection up to 800%
  • Supplied with a 10 ft. (3 m) shielded cable. Optional lengths are available
  • Custom sensor designs can be developed to meet specific applications requirements.
