Add Angle Measurement

ATP digital torque multipliers offer the additional option of angle measurement capabilities. This is achieved with the inclusion of an internal angle encoder providing angle readings of less than 1 degree.

What Is Angle

In addition to strict torque control processes, engineers have begun implementing angle control as a means of preloading fasteners with improved accuracy and repeatability. Torque-angle procedures call for the repeated loosening and tightening of a fastener to a snug torque with a final subsequent turn of nut to a specified degree and minute value. The resultant peak torque is then recorded and cross-checked to fit within an acceptable window. By cycling the joint repeatedly prior to final loading, relaxation and friction effects can be mitigated as the contact faces are pulled together before the initial torque is applied. Monitoring the final torque against the applied angle can tell us if we have encountered excessive friction losses or other interferences in the assembly. While still not completely eliminating these factors, the introduction of angle can provide better insight and understanding of application preload to further reduce torque uncertainty in comparison with traditional torque-only methods.
