Abstract

A stiffness measuring device characterized in that the meter comprises deformable coupling means arranged between output means and input means to transmit energy from the input means to the output means, first sensing means that respond to the input means to emit a first series of signals representative of the displacement of the input means, second sensor means that respond to the output means to emit a second series of signals representative of the displacement by the coupling means of the output means, and comparative means that respond to the first and second series of signals to determine the difference in the number of signals in the first and second series of signals over a reference number of consecutive signals in the second series of signals, when power is transmitted by the coupling from the input means to the output means, said difference being a function of stiffness.
