In the field of materials science and industrial inspection, hardness is a key physical property directly related to a material's wear resistance, strength, and service life. The magnetic hardness tester, as an advanced hardness testing tool, has received widespread attention for its unique measurement method and efficiency. This article will detail how a magnetic hardness tester works.
The magnetic hardness tester from TX, one of the professional portable hardness tester suppliers, mainly consists of a magnetic device, probe, display, and control unit. The magnetic device is used to attach the probe to the surface of the material to be tested, while the probe is the part that comes into contact with the material's surface and applies thetest force. The display shows the measurement results, and the control unit is responsible for controlling the entire testing process and processing the data.
The testing process of the magnetic hardness tester roughly involves the following steps:
Preparation Stage: First, place the magnetic hardness tester on the surface of the material to be tested, ensuring that the probe is perpendicular to the material's surface. Then, use the magnetic device to firmly attach the probe to the material.
Applying Test Force: The control unit drives the probe to apply a predetermined test force to the material's surface. Thistest force is usually determined based on the hardness of the material to be tested and the testing requirements.
Holding and Releasing: Under pressure, the probe forms a certain contact area with the material's surface. At this time, the control unit will maintain this for a while to ensure full contact between the probe and the material's surface. Subsequently, the control unit will release the pressure, lifting the probe from the material's surface.
Measurement and Recording: During the lifting of the probe, the magnetic hardness tester measures parameters such as the friction or displacement between the probe and the material's surface, and calculates the material's hardness value based on these parameters. Rockwell hardness values will be displayed on the screen.
The portable hardness tester working principle is based on the Rockwell hardness testing principle. During the testing process, the indenter applies a predetermined pressure to the surface of the material and, after maintaining it for a certain time, releases it. Under pressure, the indenter presses into the surface of the material, forming a certain indentation. The depth and shape of the indentation are related to the material's hardness. The magnetic hardness tester from TX, one of the leading rockwell hardness tester manufacturers, measures relevant parameters of the indentation (such as depth, area, etc.) and combines them with the pressure applied by the indenter to calculate the material's hardness value using the Rockwell hardness formula.
Due to the use of magnetic attachment technology, theinstrument can be firmly attached to the surface of the material to be tested, thereby improving the accuracy and stability of the test. Moreover, this rockwell tester for sale is easy to operate, provides quick testing, and has strong adaptability, widely used in hardness testing of pipelines in the petroleum, natural gas, and power industries, as well as in other industries such as mold hardness testing.
As an advanced hardness testing tool, the magnetic hardness tester plays an important role in the fields of materials science and industrial inspection with its unique testing method and efficiency. With continuous technological progress and expanding applications, the performance and functions of the magnetic hardness tester will further improve and be enhanced. In the future, we have reason to believe that the magnetic hardness tester will showcase its strong application value in more fields.
