PCE Instruments PCE-3500 Hardness tester Brinell, Vickers, UCI, Rockwell, Leeb , UTS (MPa)

The ultrasonic hardness tester is intended for the non-destructive hardness measurement of metallic components. The ultrasonic hardness tester works according to the ultrasonic contact impedance method. The UCI method stimulates a Vickers diamond at the test probe with self-resonance. By pressing on the test probe, the oscillation frequency is attenuated according to the hardness of the surface and depending on the E-module of the material and the contact surface. Based on the resulting frequency shift, the hardness of the surface can be determined taking into account a material characteristic curve.

The ultrasonic hardness tester works without any damage. Although a microscopic impression is created in the surface, it is not normally visible to the eye. Due to the low penetration depth of the Vickers diamond, the ultrasonic hardness tester is especially suitable for edge-layer hardened components such as those produced during nitriding or induction hardening. Typical applications include punching tools, presses, thin-walled components, gears, turbine blades, Camshafts or welds. The ultrasonic hardness tester is also suitable for many other applications in the field of hardness testing. Different applications can be covered thanks to exchangeable probes with different contact forces.

After measuring the hardness of a component, the ultrasonic hardness tester shows 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. Since the ultrasonic hardness tester has an internal memory, the measurement data can be evaluated after the measurement with a software.
