Fluid Displacement Comparators
Fluid Displacement Comparators
Fluid
displacement comparators work on the principle of displacement of fluid. These
comparators find only limited applications in metrology.
Working Principle:
The component to
be checked is placed below the measuring plunger. If any deviation in size of
the component then the diaphragm deflects a small quantity of fluid. This small
quantity of deflected fluid will cause to raise fluid in capillary tube. A
scale is available with the capillary tube with indicates the limit points of
fluid raised or lowered.
