Real-Time Residual Material Detection for Lithium Battery Unwinding Systems
In lithium battery production, real-time monitoring of residual electrode roll material is critical to reduce waste and ensure stable material supply during continuous processing.
SinceVision’s SD-C400 laser displacement sensor dynamically measures roll diameter and calculates remaining material length with high accuracy. With a wide 200–600mm detection range and 0.2mm repeatability, it supports reliable monitoring across various roll sizes. Improving production efficiency and reducing downtime from unexpected material exhaustion.
