How many types of ultrasonic hardness testing are there?

Ultrasonic hardness testing is a non-destructive method suitable to determine the hardness of materials. It utilizes high-frequency sound waves to measure the resistance of a material to indentation or deformation. This testing technique has gained popularity in various industries due to its accuracy, efficiency, and ability to assess the hardness of different materials.

In this blog post, we will explore the various types of ultrasonic hardness testers available in the market today. These testers differ in terms of their design, functionality, and application. So, you can learn more about different types of ultrasonic hardness tester options here.

Types of ultrasonic hardness testers available out there

Let’s have a look at the different types of ultrasonic hardness tester options available out there.

So, here we go:

1. Motorized ultrasonic hardness tester

The motorized ultrasonic hardness tester is a sophisticated testing instrument that features a motorized probe. This probe automatically applies and removes the load during the testing process. It provides precise and consistent test results. Therefore, it is an ideal type of ultrasonic hardness tester for high-volume testing and professional laboratories.

If you want to invest in a reliable motorized ultrasonic hardness tester, consider the SU-300M Motorized Tester. It offers too small contact indentation. Additionally, this ultrasonic hardness tester doesn’t only work with motorized probes but also works efficiently with manual probes.  

2. Manual ultrasonic hardness tester

The manual ultrasonic hardness tester is a portable and user-friendly device. It requires manual operation to apply the load and measure the indentation depth. This type of tester is commonly suitable for on-site testing, where portability and convenience are essential.

The measurement process of a manual ultrasonic hardness tester involves positioning the manual measurement probe by hand. Then, you need to push it down onto the material. After a certain time, the probe is lifted, and the indentation depth is measured. This method allows for quick and easy hardness testing without the need for complex setup or calibration. Manual ultrasonic hardness tester is usually suitable for a wide range of applications.

3. Roller ultrasonic hardness tester

The roller ultrasonic hardness tester has a specific design for testing the hardness of cylindrical or curved surfaces. It utilizes a roller probe that can conform to the shape of the material being tested, ensuring accurate and reliable results. This type of tester is commonly used in the automotive, aerospace, and manufacturing industries.

The roller ultrasonic hardness tester is particularly useful in industries where cylindrical or curved components are common. For example, it can be used to test the hardness of engine components, such as crankshafts or camshafts. In the aerospace industry, it can be used to assess the hardness of curved surfaces on aircraft parts.

One key advantage of the roller ultrasonic hardness tester is its accuracy and reliability measurements on curved surfaces.

4. Dynasonic ultrasonic hardness tester

The Dynasonic ultrasonic hardness tester is a versatile device that combines the principles of both ultrasonic and dynamic hardness testing. It measures the material's resistance to deformation by applying a dynamic load and analyzing the resulting ultrasonic waves.

One of the key advantages of the Dynasonic ultrasonic hardness tester is its ability to provide accurate hardness measurements on various types of materials. It can be used for testing metals, alloys, composites, ceramics, and even some plastics. It makes it a versatile tool for industries such as manufacturing, engineering, and research.

When selecting a Dynasonic ultrasonic hardness tester, it is important to consider factors such as:

· The load range it can apply

· The frequency of the ultrasonic waves generated

· Accuracy requirements

· Specific material types it can test.

5. Portable ultrasonic hardness durometer

The portable ultrasonic hardness durometer is a compact and lightweight device that offers convenience and flexibility. It features a battery and you can easily carry it to different testing locations. This type of tester is commonly used in field inspections, where quick and accurate hardness measurements are required.

SVR-110H Portable Durometer is a highly suitable option for people seeking a reliable ultrasonic hardness tester. It uses UCI to make at-the-spot hardness testing.

Things to consider when choosing an ultrasonic hardness tester

Here is what you need to consider when choosing the right ultrasonic hardness tester:

· Consider the type of material you will test and ensure that the selected tester is compatible with it.

· The level of accuracy and precision required for your hardness testing is an important consideration. Some testers offer higher accuracy and repeatability than others. Assess your specific requirements and choose a tester that meets your accuracy needs.

· Consider the environment in which the hardness testing will take place. If you require portability and on-site testing, a portable ultrasonic hardness tester may be the best option. In contrast, if you have a dedicated testing laboratory, a motorized or manual tester may be more suitable.

· Different hardness testers use different test scales to measure hardness. Ensure that the selected tester offers the appropriate test scale for your specific application.

Final Thoughts

Ultrasonic hardness testing has revolutionized the way of conducting hardness measurements. Different types of ultrasonic hardness testers’ availability allows professionals to choose the most suitable instrument for their specific requirements.
