Ultrasonic Hardness Tester series

Product catalog summary

Overview
The HRZ-6B is an advanced, intelligent ultrasonic hardness tester designed for nondestructive testing. It utilizes ultrasonic sensors and microcontroller technology to measure hardness with high precision. The device supports Brinell, Rockwell, and Vickers hardness conversions and is suitable for various materials, including metal sheets and components with special shapes.

Features
- Nondestructive testing
- High speed and precision
- Simple operation
- Suitable for finished pieces, metal sheets, and large or uniquely shaped parts

Basic Principles
The tester uses a sensor bar to apply uniform contact pressure to the specimen. The resistance encountered by the sensor varies with the hardness of the specimen, altering the ultrasonic signal received. The method measures frequency changes to determine surface hardness. Adjustments can be made for different elastic moduli using standard test blocks.

Catalog excerpts

1. OVERVIEW Production of HRZ-6B intelligent nondestructive ultrasonic hardness tester is a measuring rod by means of ultrasonic sensors to measure the hardness of a high-tech, intelligent new tool. As the instrument uses an advanced sensor systems and micro controller technology, so the instrument in the function and structure is completely different from the traditional ultrasonic hardness tester, especially in the realization of Brinell, Rockwell, multi-dimensional standard hardness conversion, multi-point equilibrium value The calculation shows that the exact precision, the use of simple procedures and many other aspects have been further refined and improved,The instrument is mainly used in Rockwell hardness measurement can also be converted to the corresponding Brinell, Vickers hardness to display. Features: No damage on the surface of the workpiece, high speed, simple operation and high precision. The finished piece, metal sheet, metal sheet (including the nitrided layer, carburized layer, plating layer, etc.), as well as easy movement of large parts and difficult to remove the special shape of parts and components, can be 100% directly hardness measurement. THE BASIC PRINCIPLES A uniform contact pressure, the sensor bar to the top of the pressure head and the specimen surface contact, the hardness of specimens of different rods produced by the resistance of the sensor is different from feedback received ultrasound signal change. Ultrasonic hardness testing method is through receiving different ultrasonic sensors to measure the frequency change the hardness of the specimen surface. The elastic modulus of specimens of different, there will be some impact, if the same standard modulus test block can be adjusted to eliminate this effect. 2. TECHNICAL DATA Indication range HRC10-70, HB100-550, HV100-999 Rockwell hardness is displayed, display the range and Display accuracy precision of 0.1° Indicating accuracy ± 1 unit of Rockwell C hardness Pressure head specification 136°diamond pyramid
