Digital Brinell Hardness Tester

YTS-BHT-D

Application Standards

ASTM E10, ISO6506-2, GB/T231.2

Description

In accordance with the ASTM E-10 industry standard, the Digital Brinell Hardness testing system is suitable for testing surfaces of materials (like castings or forgings) that are too rough for other methods. It offers a test load ranging from 62.5kgf to 3000kgf and features a closed-loop system, ensuring the highest accuracy in load control. This system guarantees precise application of test force.

The Brinell Hardness Tester units are standalone and easily adaptable equipment. They can be upgraded to include the Brinell Digital Scope with Automatic Measuring Software. This combination, along with the auto-indentation capture function, ensures the most accurate and error-free results.

Applications

Brinell hardness testing is commonly employed for materials characterized by large grain size, rough test surfaces, or material inhomogeneity, including castings, alloys, and forged components. This method, named after Swedish engineer Johan August Brinell, involves indenting a material surface with a hardened steel or carbide ball under a specified load, typically ranging from 1 kgf to 3000 kgf. The diameter of the resulting indentation is measured, allowing for calculation of the Brinell hardness number (BHN). This approach offers advantages in evaluating materials with non-uniform structures or rough surfaces, providing valuable insights into their mechanical properties and suitability for various industrial applications.Top of Form

Features

  • Innovative closed-loop technology: The Brinell hardness tester incorporates the latest load cell technology, utilizing a closed-loop control unit with a DC motor, load cell, and electronic measurement and control unit to ensure highly accurate Brinell hardness measurements at all test loads up to 0.5%. This eliminates common load overshoot or undershoot seen in traditional dead weight or open-loop systems.
  • Reduced weight: The entire weight of the Brinell Hardness tester is 50% less than traditional dead weight testers, enhancing portability and reducing sensitivity to misalignments caused by vibrations.
  • Fully automatic test cycles: The Brinell hardness tester features fully automatic test cycles, including holding, load application, and unloading, improving reproducibility by eliminating operator influence.
  • Selectable dwell times: Dwell times can be easily selected via the screen interface, with clear display of indenter, load, and other test information on the large LCD screen.
  • Test load selection: Test load selection is facilitated by a keyboard and LCD screen interface.
  • Brinell Hardness Calculator (BHC): Simplifies Brinell hardness value calculation for added convenience.
  • Material-specific ratios: The directions for selecting ratios according to materials and hardness range can be displayed on the screen.
