- A force measuring devices generally measures the applied
force from the proportional deformation of a spring
element: the larger the force, the more this element
deforms.
Proving ring is a metal ring with a dial gauge or
micrometer in the centre to measure the ring’s
deformation during force application. (mechanical
method is used to achieve reading this deformation)
Load cell is a transducer that is used to convert a force
into electrical signal. (the deformation is obtained by using
stain gage and electronic circuit)
