The Leybold Vacuum Pressue Gauge is commonly called a (BOURDONVAC, DIAVAC, capsule vacuum gauge) the pressure is determined directly by recording the force acting on the surface of a diaphragm. In this case of direct (or absolute) pressure measurements, the readings obtained through the vacuum gauge are independent of the type of gas and the pressure which is to be measured.

This vacuum gauge contains a hermetically sealed, evacuated, thinwalled diaphragm capsule which is located within the instrument. As the vacuum pressure reduces, the capsule bulges. This movement is transferred via a system of levers to a pointer and can then be read off as the pressure on a linear scale.The pressure range is approx. from 1 to 100 mbar (0.75 to 75 Torr). This gauge connects with a hose nozzle DN10 mm 3/8in.This Model 16068 has the integrated isolation valve for use on packaging machines.
