Degeneration Effects of Thin-Film Sensors after Critical Load Conditions of Machine Components

In the context of intelligent components in industrial applications automotive, energy or construction sector, sensor monitoring is crucial for security issues and to avoid long costly downtimes. This article discusses component-inherent thin-film sensors this purpose, which, contrast conventional technology, can be applied inseparably onto component’s surface via sputtering, so that a maximum information about condition generated, especially regarding deformation. examines whether continue generate reliable measurement data even after critical component loads have been applied. extends their field use concerning plastic deformation behavior. Therefore, any change properties necessary ongoing elastic strain measurements. These novel fundamentals are established constantan gauges platinum temperature on steel substrates. general, k-factor decrease an increase coefficient resistance with increasing could observed until failure above 0.5% (constantan) occurred (1.3% platinum). Knowing these values makes it possible measuring strains load conditions machine terms Additionally, method sensor-data fusion clear determination presented.
