What is Ultrasonic Hardness Testing
The UCI method uses the same pyramid-shaped diamond as a conventional Vickers hardness tester. Unlike Vickers testing, no optical evaluation of the indentation is required, enabling fast and portable measurements. The test load is applied by a spring and typically ranges from 1 to 5 kg of force (HV1 – HV5). As the diamond is forced into the material, the frequency of the rod oscillation changes in response to the contact area between the diamond and the material under test. The instrument detects the shift in frequency, converts it to a hardness value which is immediately displayed on the screen. PHASE II ultrasonic portable hardness testers are capable of measuring the surface hardness of a broad variety of metals on flat, round, thin or large surfaces.
The 10 N sensor measures a roughness of less than 3.2 µm and the one with 98 N measures a roughness of less than 15 µm. Hardness testing is absolutely critical in many industries and phases of manufacturing. Detecting defects during this process can save thousands of dollars and a lot of headaches later due to product or structural failure. Instead, ultrasonic contact impedance hardness testing want to use a non-destructive testing method, like Ultra Sonic Hardness testing.
SU-300H can not only work with the manual probes, but also work with the motorized probes, which is able to meet the different application in light of different condition of surface roughness. ASTM C724 test method is used in analyzing the quality and ease of maintenance of a ceramic decoration on architectural-type glass. ASTM E2141 test methods provide accelerated aging and monitoring of the performance of time-dependent electrochromic devices integrated in insulating glass units . This test helps to understand the relative serviceability of electrochromic glazings applied on ECD. The ASTM D2674 test is a standard test method for the analysis of sulfochromate etch solutions used in the surface preparation of aluminum.
Two notable advantages over sEMG-based sensing are that the proposed sensing method is far less sensitive to skin contact conditions and that it can measure muscle contractions through one’s clothes. Being capable of body force estimations noninvasively, the proposed sensing method is attractive in the field of exoskeleton robots or human-augmentation systems. Automatic motorized test probe for the PCE-5000 hardness tester with a test force of 10N. The motorized test probe can be used in conjunction with the test rig for the hardness testing of chromium-plated or copper-coated printer rolls. Automatic motorized test probe for the PCE-5000 hardness tester with a test force of 3N. Automatic motorized test probe for the PCE-5000 hardness tester with a test force of 5N.

Brinell , etc.) for hardness control of steel and other metals ; – Possibility of hardness control of items that are inaccessible for stationary hardness … Detection of breast cancer and regular monitoring of the response to neoadjuvant chemotherapy are important issues for large numbers of women. To address these needs, we developed a new instrument for examination of stiffness of the breast using haptic sensor technology.
