Contact-free cleanliness inspection of parts’ surfaces
The hand-held measuring device SITA CleanoSpector is highly suited for cleanliness inspection of parts to assure product quality as well as follow-up processes such as adhesive bonding, coating, welding, hardening and bonding.
Unwanted, filmic contamination such as oils, greases, cooling lubricants and release agents are measured by determining the fluorescence intensity.
The SITA CleanoSpector is easy to use and optimal for quality assurance directly in the manufacturing process.
Features
- Mobile and robust device for flexible use at the process and in the laboratory
- Intuitive operation: simple and fast operation at the push of one button
- Device with easy to handle sensor head and display unit enables measurement with a small contact area as well as different application possibilities
- Check and adjustment with calibration standards
Measuring Principle
The measuring method uses the characteristic of organic substances to fluoresce. UV light is focused and radiated onto the surface. The contamination fluoresces. The intensity of the fluorescence increases with the layer thickness of the contamination. The intensity is measured in RFU: Relative Fluorescence Unit. The lower the measuring values in RFU, the cleaner the surface.
Applications
- Cleanliness inspection of metal parts after machining
- Inspection of functional surfaces after selective cleaning
- Inspection for residues of release agent on aluminium die-cast parts prior to adhesive bonding
- Monitoring the cleanliness of metal parts before laser welding
- Inspection for filmic contamination on parts in medical- or vacuum technology
- Detecting residual agents and encapsulation material on bond pads before bonding
- Surface inspection on electrical contacts after stripping of isolation material
- Inspection for sufficient layer thickness when applying corrosion protection oils or primer prior to adhesive bonding
