For employing Condition Based Maintenance (CBM) systems, laying cables for transmitting signals and supplying power have been a problem. We have developed a condition monitoring system using wireless signal transmission combined with energy harvesting, which eliminates the need of cables. Use of wireless signal transmission eliminates the need of signal cables, but does not eliminate power cables. Energy harvesting, a technology obtaining energy from environment, solves the problem of power cables, though the electric power obtained by energy harvesting is not sufficient for conventional sensor systems for CBM. We have solved this problem by using a low power Micro Controller Unit (MCU) and low power sensors applying Micro Electro Mechanical Systems (MEMS) technology. The condition monitoring system performs seismic monitoring and vibration monitoring of rotating machines.
