Elcometer BG80 Bolt Tension Monitors

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 range of bolt tension monitors accurately measures this elongation allowing the gauges to accurately measure time (nanoseconds), elongation, load, stress, and %strain of the bolt.

The Elcometer BG80 bolt tension monitor is available in two models: BG80DL and BG80TDL.

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 range 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.
