HUBER PTF 4000 – Dipping-Bell Primary Pressure Standard class 0.02%
The PTF4000 Pressure Primary Standard is a state-of-the-art application of this basic principle.
The dipping-bell, made from a thin-walled stainless pipe-closed on the top, is located as under-load on a precision balance with electronically controlled force compensation. The pressure to be measured passes through two tubes through the sealing liquid under the bell, thus resulting in a buoyancy.
The resulting force is measured and compensated electronically. Complex control algorithms compute under consideration of environmental factors (optional) high precision and reproducibility.
