Swing

The continuous monitoring of vibration caused by motors and machinery as well as decentralised power production plants as wind power plants are increasingly gaining economic significance. Continuous on-line monitoring and technical diagnosis help to improve the availability of aggregates, since service and repair schedules may be optimised.

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 authorised 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.
