Presentation on 10th September 2018 by Yan Yan at the 57th Annual British Conference on Non-Destructive Testing, in Nottingham. Based on the paper of the same name authored by Yan Yan and Isaak Tsalicoglou of Proceq SA (Switzerland). Since its development in 1961, the Ultrasonic Contact Impedance (UCI) method has been widely used in portable hardness testing. The latest generation of UCI probes are is equipped with an internal force sensor which allows the test load to be adjustable. It also allows the continuous monitoring of the manually-applied force, enabling the system to provide user guidance during the measurement. A key development with these UCI probes is the introduction of wirelessly connectivity using Bluetooth 4.0, mobile devices and cloud back-up. The aim is to enable real-time data sharing and efficient collaboration with remote supervisors and experts. This presentation demonstrates some of the practical benefits made possible with this concept and explains how this can significantly improve the quality of the data being collected.
