FEATURES OF THE NORBAR USM-II

The Norbar USM-II, Ultrasonic Bolt Meter, defines the State of the Art in the measurement of the actual clamp load produced by tightening a fastener. The USM-II can measure clamp load or the resulting elongation extremely accurately in bolts of virtually any material from 25mm to 24 metres in length.

Through the use of digital signal processing and automated signal diagnostics the USM-II minimises operator training and preparation. The Norbar USM-II provides state of the art hardware and software to achieve measurements with Maximum automation, minimising operator interpretation. Offering digital recordation and transmission of data, as well as calibrated analog signal output, the USM-11 offers a complete system for measurement, recordation, and control of bolt tension in the most demanding applications.
