PCE Ultrasonic hardness tester PCE-3500-98

The ultrasonic hardness tester is used for non-destructive hardness measurement of metallic components. The ultrasonic hardness tester works according to the Ultrasonic Contact Impedance method. In the UCI method, a Vickers diamond on the test probe is excited with natural resonance. By pressing on the test probe, the vibration frequency is damped depending on the hardness of the surface and the modulus of elasticity of the material and the contact surface. The hardness of the surface can be determined from the resulting frequency shift, taking into account a material characteristic curve.

The ultrasonic hardness tester works non-destructively. Although a microscopically small impression is made on the surface, this is not normally visible to the eye. Due to the low penetration depth of the Vickers diamond, the ultrasonic hardness tester is particularly suitable for surface-hardened components such as those produced during nitriding or induction hardening. Typical applications include punching tools, presses, thin-walled components, gear wheels, turbine blades, camshafts and weld seams. However, the ultrasonic hardness tester is also suitable for many other applications in the field of hardness testing. Thanks to interchangeable probes with different contact forces, a wide range of applications can be covered.

After measuring the hardness of a component, the ultrasonic hardness tester displays various statistical values such as min/max and average values. Standard deviation and other coefficients can also be determined, and a histogram can also be displayed. As the ultrasonic hardness tester has an internal memory, the measurement data can be analysed after the measurement using software.
