NID - non impact diagnostics is a modern method of detection and evaluation of operational states and characteristics of industrial devices.
Non impact diagnostics is a method of identification of a system's state based on the evaluation of process data collected during standard operation, that is, without operation impact.
NID can mainly be used in continuous operations of industrial devices where every incidental shutdown causes operational problems and related financial losses. In such devices it is necessary to be particular about the correct system state diagnostics and about ensuing servicing and maintenance planning. This is the only way to ensure safe and reliable system operation, leading to maximum operational efficiency.
