Removing contamination off cleaning and rinsing bath in the industrial part cleaning industry ensures a long bath operation time and high parts cleanliness. The SITA ConSpector can measure the bath contamination in cleaning and rinsing baths at the plant or in the laboratory. The measuring result is available within a few seconds.
Sudden process disturbances such as the breakdown of the filter unit or a high increase of the contamination level in the bath can be immediately identified and resolved at the same time. Cleaning bath treatment measures can be carried out and controlled according to the application. The cleaning process can be carried out within allowed limit values leading to a reliable cleaning result. Controlling the rinsing steps with regard to the carry-over effect of contamination or cleaning chemicals avoids a further contamination of parts.
Examples for detectable contamination:
- Cooling lubricants
- Rolling oil
- Deep drawing oils
- Release agents
The fluorescence of the bath contamination (e.g. oil drop) is excited by a UV light source. A photodiode in the sensor head of the SITA ConSpector measures the intensity of the radiation emitted by the fluorescence at a defined wave length in the blue light spectrum. The strength of the fluorescence depends on the contamination level per volume.
The SITA ConSpector works on the confocal measuring principle. The excitation light and the light emitted by the fluorescence follow the same parallel ray path. The measurement of the contamination level can be easily realised by immersing the remote immersion probe into the bath sample.
