VD81 1600 to 1 mbar Ceramic Sensor Application Example Vacuum packaging increases storage life of food products by a factor 3 to 5; the package is first evacuated and then hermetically sealed. To check correct performance a battery operated VD81 is vacuum-sealed instead of the product at regular time intervals. During the packaging process the instrument stores the achieved minimum pressure. After the VD8 vacuum meter is taken out of the packing this minimum pressure can be displayed and checked. • Setup and check of vacuum plants • Analysis instruments • Chemical engineering • Substitution of...
