New fast NGO3 measuring head for contact free oil layer thickness measurement. New materials and more complex components require ever greater precision for the forming process. The lubricating film on steel and aluminum sheets must be adapted to the process. Tool life is to be increased, the number of missing parts in production is reduced and efficiency is increased.
With the new and fast online oil layer thickness sensor NGO3 you continuously determine the oil layer thickness during the process. You receive the measured values in real time. As a numerical value in g / m², as a graph or as a color carpet, you can immediately see the lubricating film covering with which the material is coated.
You can react directly to under- or over-oiling, flat or partial, and avoid faulty production, process downtimes and increased tool wear.
Statistics are created on the collected data of the production, including the oil layer thickness. This allows conclusions to be drawn as to which oiling is used to ensure the highest level of process reliability, the lowest number of missing parts and the longest tool life. For some subsequent processes e.g. coating or painting measures must be ensured and verified that there is no oil.

Areas of application
The standard measurable oil thickness is between 0.05 and 6 µm (approximately g / m2) oil layer thickness. Calibrations are standard for:
Using the Lambert Beerschen law, the NGO3 determines the oil layer thickness.
The thickness of the oil layer is directly related to the absorption of the light. The light rays penetrate the oil layer twice. The specific wavelengths are partially absorbed by the oil and evaluated. This measuring principle works largely independent of the type of oil, so oil mixtures do not affect the measurement results accountably.
0.02-6 g / m²
0.10 – 0.5 g / m²: +/- 0.025 g / m²
0.5 – 2 g / m²: +/- 0.2 g / m²
> 2 g / m²: +/- 10% of the measured value
<0.0010 g / m²
up to 0.01 g / m²
