Materials such as fabric, copper foil, battery separator film, optical film, and corrugated board require accurate length control during slitting and rewinding to meet customer specifications and reduce waste.
Traditional encoder wheels rely on contact measurement and can be affected by slippage, tension, and long-term accumulated errors. DALA Metrology’s DLS Series uses non-contact optical measurement to provide real-time current speed, average speed, and total length, with accuracy up to ±0.05%.
DALA’s laser length measurement system is based on the laser Doppler principle, with a measurement accuracy of ±0.05% and repeatability of ±0.02%.
The system has minimum size requirements for the measured product. Currently, the smallest verified cable diameter is 0.2 mm.
Yes. DALA systems are already used in a variety of fixed-length cutting applications and support output signals such as pulse and digital outputs to work with cutting machines.
The final configuration should be confirmed based on line speed, accuracy requirements, cutting method, and on-site conditions.
Provides end-to-end support from product selection to production line operation through on-site guidance and after-sales technical support.
