HAUG lonization -for the dtection of perforations
Applioations
The PZ 3 perforation counter is mainly applied in the manufacturing of plastic bags. The contactless dtection of perforations allows the number of bags/batches to be determined and indicates when the material rolls need to be changed.
Mode of op驩ration
Sparks are generated at the point of the perforation of the film by means of a high-voltage lectrode (counting lectrode) and a suitable earthed/grounded counter-electrode. Th驨se sparks are interpreted and counted by the logic circuit integrated in the PZ 3 perforation counter and indicated visually on the display through a light-emitting diode. The counting puises transmitted by an opto-coupler can be interpreted by an external counter and may be used for activating other machine functions (such as the control of reversing winding machines and cutting machines).
Direotions for installation
The counting lectrode must be mounted above the material web at a distance of approx. 10 to 20 mm and centered over the perforations to ensure the perfect functioning of the PZ 3. An earthed/grounded counter-electrode below the material web (e.g. earthed mtal drum) must be in physical contact with the foil opposite the counting 驩lectrode.

Speoial features and advantages
 The PZ 3 perforation counter offers the possibility to capture up to 900 counting puises per minute. This corresponds to a counting rate of 15 counting puises per second (15 Hz).
Օ The duration of the counting impulses is adjustable from
5 to 1000 ms. This helps to suppress subsquent spark-overs that may be triggered by "holes" in the film and should not be counted.
 The high voltage applied to the counting 镩lectrode is infinitely adjustable from 2.4 up to 17 kVDC.
 The external release of the output voltage can be activated through a voltage-free contact, so that high voltage is applied to the counting թlectrode, for instance when the material web is moving.
