MODEL:HBA-3000S, Separated CCD Camera style Conforms to: ISO6506, ASTM E-10
The Brinell hardness testing creates the largest indentation
comparing all other hardness testing methods. It is able to reflect
the comprehensive features of the material, and is unaffected by
the microstructure and inhomogeneous of the specimen. So it with
high precision and widely used in industry such as metallurgy,
forging, casting, unhardened steel and nonferrous metals, as well
as in the laboratories, universities , and scientific research
HBA-3000S can combine HBI-10M or HBI-10A Brinell indention tester
to compose an advanced automatic Brinell testing system. Or
matching a 20X optical microscope to form an economical
Innovative closed-loop technology. The tester incorporates the
latest load cell technology. The test load is applied via a
closed-loop control unit with a load cell, a DC motor and an
electronic measurement and control unit. The result is highly
accurate measurements at all test loads up to 0.5%. The common load
overshoot or undershoot as known from traditional dead weight, or
open-loop, systems is eliminated. The absence of mechanical weights
not only eliminates friction problems but also makes the equipment
less sensitive to misalignments caused by vibrations.
The whole weight of the tester is 50% less than the traditional
dead weights type tester.
Test load selection by keyboard and LCD screen. No need of handling
heavy weights or cleaning the messy oil.
Fully automatic test cycles. The hardness Tester features a fully
automatic test cycle, load application, holding, unloading, is
performed fully automaticly. This greatly improves reproducibility
of test results since operator influence is eliminated.
Selectable dwell times by screen. The indenter, load, and other
test informations are showing clearly on the large LCD screen.
The directions for 0.102F/D2 ratios selecting according to the
materials and hardness range can be showing on the screen.
Separated CCD Camera make the test more flexible and movable. The
special Brinell indention measure system can measure the Brinell
indention accurately, quickly, reliably. It is a new measuring
method by using CCD camera to capture the indention image, instead
of reading diameter from optical microscope.
