      With a choice of display and measurement modes, the user can select the most appropriate option for their needs; Elongation, Load, Stress, and %Strain, RF, Rectified, Large Digits with Limits Bar.

      When nuts and bolts are fastened together under load the action of tightening the nut increases the force applied to the bolt causing elongation.

      By using ultrasonics, bolt tension monitors are not affected by temperature, friction or resistance factors affecting the accuracy of standard torque measurement techniques - giving the BG80TDL accuracy within 0.0001mm (0.00001 inch).

      Using the gauge's USB interface together with the optional shut off accessory the gauge can be programmed to automatically stop the tightening process when the appropriate load has been applied.

      Features:

      • Range of display & measurement options including: Elongation, Load, Stress, and %Strain, RF, Rectified, Large Digits with Limits Bar
      • BG80TDL features temperature compensation to counteract measurement irregularity caused by temperature change
      • Data storage capability: 4GB internal memory
      • Auto Set feature automatically optimizes detection and adjusts display
      • Hi/Lo Alarm tolerance limits work in conjunction with the data port

      How do Bolt Tension Monitors work?

      How to use a Bolt Tension Monitor

      As a fastener is tightened it stretches (elongates) in length.


      Manual torque wrenches measure the force applied when tightening a fastener, the accuracy can be affected by temperature, friction and resistance.


      As the BG80TDL ultrasonically measures the change in length accurately determining the applied load of a fastener as it is tightened, they are not affected by these factors.
