Vibration monitoring systems
To monitor sensitive drive components, structure-borne sound monitoring systems are employed. These systems are equipped with a robust piezoelectric sensor as a vibration sensor. The sensor is mounted directly on critical bearing positions of fans, pumps, and other drive components. Damage to bearings is signalised by increased noise emissions. With the help of the internally or externally arranged sensor, the structure-borne sound monitoring system measures the structure-borne sound emissions that occur during operation, which enables changes to be determined. By exceeding a freely adjustable threshold, a switch output is set which is again cancelled after the threshold is fallen below. Usually, this output to the output serves as a warning. Further outputs can be used for switching off and locking the monitored machine.
