When nuts and bolts are fastened together under load·the action of tightening the nut increases the force·applied to the bolt causing elongation.·The BG80 Series of bolt tension monitors accurately·measure this elongation allowing the gauges to·accurately measure time (nanoseconds), elongation,·load, stress, and %strain of the bolt.
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 BG80 Series accuracy within 0.0001mm (0.00001 inch).
Using the gauge's RS232 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.
