Monitoring the process parameter bath contamination

The Inline measuring technology SITA clean line BC continually monitors the bath contamination of cleaning and rinsing baths. Thus, it is possible to control bath care measures effectively and goal-oriented. Unnecessary rejects due to strong bath contamination resulting in insufficient parts cleanliness are prevented.

As plant component the measuring system can be flexibly adjusted to each individual cleaning technology and detects slight traces of contamination in rinsing baths. Interfaces enable the integration into the plant control for monitoring bath care as well as the integration into quality management systems for complete documentation of the process development.

Upon the basis of a combined analysis of process and plant, SITA application engineers develop optimal and customized SITA clean line system solutions.

Typical contamination of industrial cleaning baths such as oils and greases fluoresce when excited with ultraviolett light. The measured intensity of the fluorescence radiation increases with the oil and grease concentration. An integrated UV-LED stimulates the excitation of the fluorescence. A photo-diode measures the intensity of the resulting fluorescence radiation.
