توضیحات محصول
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 underload 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.
