Digital Torque Testers and Torque Tester Calibration Equipment

Torque tools require calibration and recalibration at intervals that assure the tools remain accurate while keeping the ownership cost of the tools at minimum. The selection of the best strategy for assuring accuracy must be followed by selection of the appropriate tester(s) and support equipment to achieve the goals.

We have two papers to assist you in strategy determination and tester selection. We strongly urge you to read them and use the information to assist in determining the best equipment for your operation. These papers are:

Static torque transducer compatibility chart

All of the torque transducers listed here are designed to work with both System 4 and System 5 Digital Torque Testers. Each has differing mounting options and/or mechanical loader compatibility. This chart will help you select the best transducer models for your application.

* Must be within torque limits of loader. Not for transducers of greater than 250 ft. lb. capacity.
** Requires optional bracket.

Torque Tester Calibration Equipment

Torque tester calibration is identical to torque tool calibration in its’ necessity, but of significantly greater technical difficulty in obtaining the required accuracy.  Here is a short list of impacting factors:

  • The rigidity and stability of the mounting base.
  • The distance from the center of the tester drive to the center of the cable of the weights.
  • Accuracy of the weights being used.
  • The gravitational variation where the calibration testing is performed is important.
  • Room temperature and humidity.
