1. Measuring head including:
a support frame,
an arm extending along a trajectory at least between a first end and a second end and including at least one probe arranged at said first end and suitable for contacting an external body,
constraint means configured to loosely bind said frame and said arm in such a manner that said arm is rotatable with respect to said frame about an axis of rotation, transverse to said trajectory, in proportion to displacements defined by the interaction of said probe with said body,
a capacitive differential sensor including:
an emitter integral with said frame and disposed in proximity of said second end,
a receiver integral with said second end, and
a computer operatively connected to said receiver and configured to determine position parameters of said receiver with respect to said emitter from a predetermined reference position value so as to determine said displacements of said probe.
