The Elcometer BG80TDL Bolt Tension Monitor uses ultrasonic technology to measure bolt elongation, offering high accuracy unaffected by temperature or friction.
The Elcometer BG80TDL Bolt Tension Monitor utilizes ultrasonic technology to measure bolt elongation accurately. Unlike standard torque measurement techniques, this method is not affected by temperature, friction, or resistance factors, providing high precision within 0.0001mm (0.00001 inch). The device measures the change in length of a fastener as it is tightened to determine the applied load.

It ultrasonically measures the change in length (elongation) of the fastener as it is tightened to determine the applied load.
No, using ultrasonics means the monitor is not affected by temperature, friction, or resistance factors that affect standard torque measurement techniques.
The resolution is switchable between 0.001mm (0.0001") and 0.0001mm (0.00001").
