Special electrode to provide perforation detection over a large area.
In order to detect perforations in a moving material web, this special electrode is equipped with a resistance per emitter. When a perforation passes the electrode, there will occur a controlled spark over. This is detected by the associated CM5 high voltage generator and is communicated with an output signal and the flashing of the red LED.
- Detection of perforations over a large area
- Detection of very small perforations possible
