MINI-MAX, Ultrasonic Bolt Tension Monitor, defines the state of the art in the
measurement of the actual elongation produced by tightening a threaded fastener.
The MINI-MAX can measure the elongation very accurately in fasteners of
virtually any material from 1/2 inch to 4 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
method. The on-board microcomputer automatically interprets this time
measurement to display the time(nanoseconds), elongation, load, stress, or
%strain from stretching a fastener.Welcome to the Dakota Ultrasonics website!We
are a manufacturer of industrial ultrasonic testing equipment most commonly used
in the petrochemical, aerospace, automotive, and other generally related
industries. The pages that follow will provide you with general information
regarding our products. If you have any questions, need technical support, or
have a request for custom items, please contact us at your leisure using the
information provided on this site.Our products are commonly used to determine
the thickness of a variety of materials by making contact with only one side of
the material being tested. They have the ability to detect very fine pits,
flaws, and porosity in materials without having to destroy the material or parts
being tested. This is done by converting the transit time of a sound wave, sent
into and reflecting back from a defect or opposite surface in the test material,
into a length measurement. This technique uses principles similar to that of
sonar.We also manufacture a line of ultrasonic bolting equipment that very
accurately measures the stress, elongation, and load in threaded fasteners.
These products are typically used in critical bolting applications where extreme
accuracy is needed. If you have any specific or specialized bolting applications
in mind, be sure to contact us to discuss your requirements in detail.
