EMG SOLID® IR

The measuring principle

Measuring principle EMG SOLID® IR

Within the infrared spectroscopy with EMG SOLID® IR the system emitts an infrared light that passes through the oil layer, is scattered back from the strip surface and passes through the oil layer again.
In doing so the intensity of specific wavelengths of the oil layer is attenuated. According to the Lambert-Beer law, the layer thickness is then calculated from the logarithm of the absorption.

The used measuring head has been developed by our partner Infralytic GmbH.
