Making a Safer World Through Accuracy and Precision

PTL Preset Torque Limiters

Preset Torque Limiters

 

Designed to be used “in-line” to limit torque for hand (static) applications. Can also be used as an overload protection device on most  applications where measuring a static overload is needed. Provides accurate process control as the unit prevents a fastener or bolt from being under and over tightened.

Repeatability within +/- 6% of pre-set torque value.

  • Various models that range from 1 to 85 lbf.in.
  • Designed to be used “in-line” to limit torque for hand (static) applications. For low torque applications.
  • Can also be used as an overload protection device on most applications where measuring a static overload is needed.
  • The rotary clucth mechanism ‘slips free’ when the pre-set torque value is reached, eliminating overtightening. The mechanism then automatically resets.
  • Pre-set using a torque analyzer.
  • Bi-directional operation and are calibrated in either the CW or CCW direction.
  • Lighweight and easy-to-use.
  • Non-length dependent. Bi-directional operation and are calibrated in either the CW or CCW direction.
