The non-destructive hardness measurement system is "an evaluation system that measures the hardness of metal materials non-destructively using magnetic sensors, making it ideal for inline inspection."
【Conventional Hardness Measurement Method】 "Traditional hardness testing requires effort, time, and disposal costs." Metal hardness testing involves the use of instruments such as Vickers hardness testers, which require cutting, embedding, and polishing to destroy the sample for hardness measurement. 【New Method Non-Destructive Hardness Measurement Method】 "By applying magnetic characteristics, hardness measurement can be easily and quickly performed." An alternating current is input into a magnetic coil sensor, and the BH curve is calculated from the induced voltage signal, allowing hardness to be estimated from the value of Hc. With the non-destructive hardness measurement method, significant reductions in inspection costs are achieved, and inline full inspections become possible, enabling effective use as quality control data. ☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆ A-SAP Industry-Academia-Government Collaboration Innovation Promotion Project has been adopted, and an interview video on joint research with Shizuoka University has been released. 【Development of Non-Destructive Measurement System for Metal Properties】 https://www.hai.or.jp/pvc/asap/project/project-232/

basic information
【Non-destructive Hardness Measurement System】 【NDH-20】 The computer and control circuit are connected with just one USB cable, making it very easy to move to different measurement locations. (The amplifier circuit is housed in a single box in the product.) Both the measurement program and magnetic sensor are originally designed, allowing us to accommodate requests for both software and hardware, and we can propose the optimal system tailored to your products. 【NDH Series】 The NDH series includes a dustproof box specification that is ideal for mass production inline, and systems that can be integrated with line equipment for communication. Additionally, since the equipment is configured with NI devices, we also offer systems that are optimal for integrating and compiling evaluation data with other data at experimental sites, as well as building integrated evaluation systems. In terms of the program, it is designed with LabVIEW, providing a wealth of measurement evaluation functions and the ability to add features.
