NON DESTRUCTIVE TESTING
NDTs are discontinuous by nature and they need specific tools depending on the required method (magnetic particles, ultrasonic, penetrant liquids, …). They are usually established by branch norms and they verify the health status of the component in that very moment.
Machinery monitoring is performed in continuous by considering functional parameters of the plant (such as temperatures, pressures, accellerations, …). Data analysis can be performed at different levels of detail basing on customer’s specifications allowing, e.g., damages diagnostics and its developing in time (prognostic). This brings to a progression in maintenance forecasts.
