Description

The Dakota Ultrasonics MAX II Bolt Tension Monitor uses ultrasonic transit time technology to measure the elongation, load, stress and percent strain of a fastener under tension. The MAX II incorporates many of the features found on other bolt tension monitors from Dakota Ultrasonics with some added benefits in terms of features, hardware, speed, and length.

The Dakota Ultrasonics MAX II Bolt Tension Monitor very accurately measures fasteners up to 100 feet in length. The measurement is achieved by determining the change in the transit time of an ultrasonic shock wave along the length of the fastener, as the fastener is tightened by any mechanical method. MAX II then interprets this time measurement into a given quantity of time (nanoseconds), elongation, load, stress, or %strain while applying a load on the fastener. Using a variety of processing and automation, the MAX II reduces operator error. With built in data recordation and supporting DakView utility software for Windows PC & MAC OSX, the MAX II offers an easy to use and reliable solution to accommodate the most difficult bolting applications.
