The following list of condition monitoring techniques, grouped by several category types, shows the extent technology has moved monitoring ahead. Condition monitoring is an advancement to know the health, safety, and performance of generators and motors where reliable, continuous, and efficient operations are required. Predictive maintenance (PdM) is a proactive maintenance technique that uses real-time asset data (collected through sensors), historical performance data, and advanced analytics to forecast when asset failure will occur. Patterns emerge from the data showing a machine part may be deteriorating or beginning to fail. During the 1990's, condition monitoring was in its infancy and mostly done to check if the routine time-based maintenance needed to have extra tasks added. There are a number of different signals that can be taken into account when monitoring mechanical assets. Below we have given tips for condition-based monitoring maintenance: 1. To enjoy the full benefits of preventive maintenance, the first step is to monitor or audit all your assets operating condition on a regular, preferably real-time basis. The data collected can be used to establish trends, predict failure, and calculate remaining life of an asset. CBM or condition-based maintenance identifies the state of the asset by sensor collected real-time data. It aims to identify significant changes or deviations that are typically indicative of a developing fault. Predictive Maintenance (PdM), also known as condition-based maintenance, evaluates the condition of equipment by performing periodic or continuous (online) equipment condition monitoring. Condition based monitoring in maintenance is focused on preventing asset failures, downtime, and unnecessary practices by monitoring asset health to determine what maintenance needs to be completed and when.
