Low cost diagnostics system dedicated to rolling bearings

This article presents low cost diagnostic system, dedicated to rolling bearings. This system can be widely used in existing machines, to improve their reliability and reduce the costs of maintenance. Low cost electronics sensors, a few microchips, a multi-meter and a programmable micro-controller, which can send data to a computer, were selected. A computer is not necessary in this system, because data can be directly presented on LCD displays; moreover, alarm levers can be signaled with flashing lights and buzzers. This shows that an operational system can be produced with low cost, which is not obvious for managers and mechanical engineers.
