Ultrasonic hardness tester with high cost-effectiveness of ultrasonic vibration

Ultrasonic hardness tester is an advanced hardness measuring instrument, which is based on the principle of ultrasonic vibration. hardnessThe probe of the meter has a pressure head at the top, which contacts the surface of the measured material during measurement, applies a certain static force, and then emits ultrasonic vibration signals to the material through the pressure head. The damping degree of ultrasonic vibration varies depending on the hardness of the material; Materials with high hardness experience rapid attenuation of ultrasonic vibration; Materials with low hardness experience slow attenuation of ultrasonic vibration. The instrument calculates the hardness of materials based on the attenuation degree of ultrasonic vibration. In practical applications, ultrasonic hardness testers have many advantages. They can measure workpieces of various shapes, whether they are large mechanical parts or small precision components, and can accurately measure them. And it has relatively low requirements for the surface of the tested workpiece, even rough surfaces can obtain more accurate results. Widely used in industries such as mechanical processing, mold manufacturing, aerospace, petroleum and petrochemical, shipbuilding, automobile manufacturing, rail transportation, pressure vessels, pressure pipelines, etc.
