UT Bolt Gauge BT1-DL

The Dakota BT1-DL Bolt Tension Monitor uses ultrasound to precisely measure fastener elongation, time (nanoseconds), load, stress & %strain.

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 Dakota BT1-DL Bolt Tension Monitor 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.
