A SYSTEM FOR AUTOMATIC PRESSURE RECORDING IN SUBLIMATION DRYING,

Abstract

The method is based on the principle of the action of a Manometer with Bourdon tubes. A Bourdon tube with its stem hermitically welded, is placed in a sublimation chamber on an elastic string. On the flat portion of the manometric coil in the 'active filament' region, two tensometer pickups are cemented on each side, which are connected to an electronic bridge. In pumping air from the chamber, the coil, filled with dry air at atmospheric pressure, undergoes general expansion which is recorded by an autoscriber.
