Monitoring a machine’s health status enables predictive maintenance, allowing industries to anticipate breakdowns and realize substantial operational savings and downtime. To determine when it is the right time to trigger a maintenance operation, the manufacturer uses parameters such as vibration, noise, and temperature measurements. In a rotating machine (engine, generator, etc.) an abnormal vibration can be a sign of a faulty ball bearing, axle misalignment, imbalance, or excessive looseness. Avoid being caught off guard and detect the very first signs of an anomaly with a low noise, high bandwidth accelerometer.
