TB 5056-02

Brinell method for measuring the hardness of large parts

Designed to measure the hardness of large-sized products according to the Brinell method, to control and sort out similar parts into hardness groups.
The drive table provides a preload of the test product during measurement.
The process of printing on the device is fully automated. The test results are recorded on the display in Brinell hardness units.

The TB5056 hardness tester automatic hardness measuring system measures hardness by measuring the depth of the restored print.
The system includes:
- photoelectric converter,
- microprocessor communication board,
- personal computer (laptop).

The software allows the operator the following:
- automatic adjustment of the measurement system according to exemplary hardness measures or the actual hardness of the test material;
- data entry that determines the test mode: numerical value of the test load, ball diameter, number of tests in a series (up to 50), values ​​of the upper and lower hardness limits;
- report on sorting into hardness groups (less, norm, more);
- calculation and indication of average values ​​of hardness in a series of tests and discrepancy of indications in percent;
- output to the printer of the unit test protocol and the test series protocol with an average hardness value;
- output to a computer.

It is possible to integrate the device into production lines.
