(a) Disadvantages of this method are:
• A long preparation time of calibration system;
• A special form of spherical cap is required;
• Difficulties of coaxial mounting of all elements
(jack, Load Cell and spherical cap);
• Low measurement uncertainty values.
• Due to that, this the method is practically unused.
(b) Substantial advantages of this method are:
• The calibration process is similar to prestressing
working process;
• The hollow form of Load Cell allows for
performance calibration without special accessories
and ensures coaxial loading of all elements of
measurement (calibration) system.
• The disadvantage of this method is a low accuracy
of the hollow Load Cells.
(c) The advantages of this method are:
• A short preparation time of calibration system;
• The possibility of using relatively high accuracy
Load Cells;
• Relatively high measurement uncertainty
