Abstract

En anordning (10) til kontroll av tettheten ved evakuerte emballasjebeholdere (1) har et klokkeformet hus (31,36) med en avstandssensor (20) og er forbundet med en undertrykkilde (23). Avstandssensoren (20) og en trykksensor (25) fører sine signaler (U,P) til en styreinnretning (28) som inngangsverdier der de to signaler (U,P) knyttes til hverandre. Fremgangsmåten til kontroll som utføres med anordningen (10) gjør det i tillegg til angivelse av tette eller utette emballasjebeholdere (1) mulig å angi det innvendige pakningstrykk (Pi) som hersker i emballasjebeholderne (1).
