Abrasion-free, non-contact measurement of sensitive surfaces
Precise length measurement on transparent film and foil for the food indutry and optical films. Length measurement on particularly smooth and almost featureless surfaces. Non-contact and maintenance-free as well as permanently accurate measurement by ELOVIS μSPEED laser encoder systems.
Typical application data:
- Path Velocity: typically up to 1,000 m / min
- Measurement accuracy with tactile measuring equipment or via drive: typically 0.5-1%
- Measurement accuracy with non-contact length measurement μSPEED: typical: 0.03%
- Amortization: 3 months, direct encoder replacement, no other modifications needed
Material examples:
- transparent foil and film, high-gloss film, food film, packaging film, furniture film and foil, …
- PET film, PE film, PP film, PVC film, PS film, PLA film, …
Foil machines which are equipped with non-contact length gauges:
- Roll Cutting Machines, Roll Cutter, Cross Cutter, Lengthwise Cutter
- Winding machines, rewinder, re-roller, doctor roller
