Web-based vibration monitoring and diagnosis
Overview
The continuous monitoring of vibration caused by motors and machinery as well as decentralized power production plants as wind power plants is increasingly gaining economic significance. Continuous on-line monitoring and technical diagnosis help to improve availability of aggregates, since service and repair schedules may be optimized.
The SWING acoustic and vibration monitoring system is a compact and low-cost measurement system based on a robust, fan-less, wall-mounted industrial PC with two slots for Apollo PCIe measuring cards.
Due to its reasonable price SWING is also suited for machines which until now have not been monitored for cost reasons. A well-documented TCP/IP interface safeguards integration into higher-level software structures. The SWING monitoring stations allow connection to a network. If required, the maintenance department, the diagnostics service supplier and further authorized persons may access the measured values or are regularly informed on operation and alarm modes by the individual measuring stations.
The cabinet contains the AC power supply, an uninterruptible power supply (UPS) including a back-up battery and a terminal block for the connection of sensor in a user-friendly arrangement . The UPS bridges short power failures and safeguards termination of the measurement, transmission of a fault report and proper shut-down of the computer in case of long-term power failures. When the power supply is restored, the system automatically resumes measurement.
We have developed a new cooling design for the SWING_MK2 monitoring station to match the requirements for the use in hot climates. The PC is equipped with a large heat sink mounted to the exterior of the cabinet door to prevent the PC from generating additional heat within the cabinet.
