The MAX, Ultrasonic Bolt Meter, defines the state of the art
in the measurement of the actual clamp load produced by tightening a threaded fastener.  The MAX can measure this load, or the resulting fastener elongation, very accurately in fasteners of virtually any material from 1/2 inch to 20 feet in length.  The measurement is achieved by determining  the change in the transit time (time of flight), of an ultrasonic shock wave along the length of the fastener as the fastener
is tightened by any method. 

The on-board microcomputer automatically interprets this
time measurement to display the load, tensile stress, or elongation resulting in the fastener.  Through the use of
high speed digital signal processing and automated diagnostics, the MAX minimizes the requirement for extensive operator training.  With built in data recordation and
reporting through RS232 and analog interface, the MAX
offers an easy to use, reliable solution to the most difficult bolting problem.
