CCS

Pinhole Detector

The IMS pinhole detector is recommended as a high-performance solution especially for rolling mills and processing lines.

The measurement method is based on the detection of finest quantities of light by CMOS photo sensors.

In this way, the CCS pinhole detector reliably detects, localises and classifies even the smallest perforations that can occur in the production of strips and foils.

detection of pinholes

optional:
– detection of strip edge defects
large hole detection
width measurement
– dynamic performance monitoring
