Dakota Ultrasonics
It is a manufacturer of
industrial ultrasonic testing equipment most commonly used in the
petrochemical, aerospace, automotive, and other generally related
industries.
Its 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.
They 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.
