Cell Thickness Gauge

The Cell Thickness Gauge is designed to measure the thickness and dimensional uniformity of battery cells. Depending on the instrument configuration, thickness measurement can be performed using mechanical contact probes or suitable non-contact measurement technologies, such as ultrasonic or electromagnetic methods.

Mechanical contact measurement uses a probe and a controlled contact force to measure the distance between the surfaces of a cell. Non-contact methods use different physical measurement principles to determine thickness. The appropriate method depends on the cell structure, surface characteristics, measurement requirements, and instrument configuration.

The Cell Thickness Gauge is suitable for lithium battery production, finished-product quality inspection, and research and development. It helps manufacturers monitor dimensional consistency, identify variations during production, and collect measurement data for battery design optimization and quality control.
