Vibration sensors are measured and monitored in the vibration level of simple rotating machinery has become economically possible, as PCH has introduced new cost effective vibration monitors. The new Compact Range of PCH monitors can be compared to electronic watch-dogs. Its a Price attractive alternative for users who want to prevent their machines from damaging vibrations. A bearing damage occurs due to undetected unbalance or misalignment of a machine and as a result, the machine runs for a very long time period and at a high vibration level. It avoids unscheduled production stops. A machine which is permanently monitored can reduce the needs of human.
