Abstract: Measuring system having a plurality of probes for measuring lengths, each probe including a probe tip connected in removable fashion relative to a casing, a transducer supplying an electric signal that is representative of the position of said probe tip relative to the casing, a digital processing unit for sampling the signal from said transducer and transforming it into a digital representation of said position, and a bidirectional interface for a wireless communication network connecting said probes with a control unit. A method including a step during which the clocks of the digital processing units of the probes are synchronized through said bidirectional wireless interface and a step during which the control unit transmits commands determining the instant at which said electric signals are sampled.
