The Development of Diamond Strength Testing System based on Microprocessor

In order to improve the quality of diamond and other super-hard materials, fast and accurate detection of its strength is significant. The System use air pressure, broken automatic detection, automatic samples, testing is completed automatically returned. By resistance strain gauges to the pressure value is converted to voltage signal, after a highprecision A / D converter chip into a numerical quantity, given to high-performance MCU processing. Sample test system can be set according to sample size, data communications, data statistics and report printing, with a large-screen LCD display, dynamic display of strength parameters of the distribution curve. System is reliable test data stability, good repeatability and high reliability.
