Brinell Hardness tests typically take place in a single area: wherever your hardness testing system is located.
In other words, you bring the specimen to the machine.
But what if you could bring the machine to the specimen?
Thanks to the portable Telebrineller hardness tester, now you can. Whether you’re in the field, a different part of your plant, or visiting another lab, the Telebrineller instrument offers completely mobile Brinell hardness tests with unparalleled convenience and accuracy – within plus or minus 2% of the BHN on the end of the NIST-certified test bars.
In this post, we’ll examine a few of the main features of the Telebrineller, including ease of operation, test accuracy, and what additional components you may wish to use during your tests.
Let’s begin by discussing what comes with the Telebrineller and how it works before diving into some of the more specific details.
What’s Included With the Telebrineller System?
The Telebrineller hardness tester is a complete testing system out-of-the-box. Included are five test bars (hardness values per your specifications) and the anvil, which is outfitted with a rubber head and non-skid resting block. The system also includes impression balls as well as all the standard parts you would expect, e.g., a spacer button, block, and spring, a bar tube, and so on. A rugged carrying case and Brinell hardness value chart are also included.
How Does the Telebrineller System Work?
Just because the Telebrineller is portable doesn’t mean it’s complex. Quite the opposite, in fact: even engineers with lower levels of experience can use the instrument with little training.
The operator begins by inserting a test bar of appropriate BNH into the device, below which is the impression ball. The tester is then placed on the specimen, whereupon the operator strikes the anvil with a 2-5 lb. hammer. A great deal of force is not necessary – the impact will be evenly distributed to the test bar and the specimen.
This impact creates indentations in both the specimen and the test bar. Using the microscope, the indentation on the specimen can be examined and compared to the Brinell hardness value chart.
At this point, the spacing button can then be used to adjust the position of the test bar, readying it for use in another test. Our test bars generally have room for 20 indentations per side, that is to say, each bar can be used for about 80 tests.
Next, let’s take a look at the big question that always comes up with regard to portable Brinell hardness testing systems: how accurate are they?
How Accurate Are Portable Brinell Hardness Testers Like the Telebrineller?
The accuracy of a Brinell hardness test—from a portable instrument like the Telebrineller or otherwise—will always be largely determined by the quality of the test bars used. The test bars are the core of any hardness system, including the Telebrineller.
The Telebrineller system includes five steel test bars, the hardness values of which are determined by you; just let us know what you need while ordering. NextGen standard steel test bars are clearly etched with a BHN. This hardness value is guaranteed to be uniform throughout within a margin of 2%. The hardness of the test bar and the specimen must not differ by more than 15%.
The microscope used will also affect the overall accuracy of the test. A manual microscope can be used for indentations made with the Telebrineller, though many users have found computer calibrated microscopes such as the BrinGen Scope to be a great boon to accuracy and operator productivity.
Note that the Telebrineller itself does not require calibration, but other components, such as the microscope may. We recommend using our calibration disc to do so quickly and easily.
Additional Components or Equipment You May Need
Depending on your usage scenario, you may need additional components or equipment. Specifically, operators who need to perform a large number of tests will need additional test bars. The test bars used don’t have to be manufactured by NextGen to function with the Telebrineller, though keep in mind our test bars are manufactured to NIST standards.
We also recommend that frequent-use operators also purchase additional impression balls. With repeated use, the ball may deform. This can lead to unrounded impressions and thus potentially less accurate results.
Operators who need to test fillet welds or other hard to reach areas may wish to purchase a Halteman Filletester. This device is used with the Telebrineller and does not change the accuracy of a test—it only makes areas easier to reach. We recommend cutting a standard test bar in half for easier operation. More information about the Halteman Filletester can be found in our Telebrineller brochure.
