Pinhole Detector

The IMS pinhole detection is ideal as high-performance solution especially for rolling mills and processing lines (e.g. for aluminum, copper and steel).

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, locates and classifies even the smallest perforations that can occur in the production of strips and foils.
