Switch and vent boxes

This easy however effective box immediately fulfils several tasks:

  • as a change-over of a measuring channel between two test parts
  • as an external roadblock to the measuring channel and external exhausting of the test part

The change-over can occur directly from the PMD02 or from a control equipment to the process. In the case of the roadblock / exhaust it concerns very effective means of holding dirty test air (filings, emulsion, water etc.) from the test circle of the testing equipment out.

Special functions as for example slow airing after a pressure check are realizable any time.
