A system and a method for the transmission of signals representative of an event include a first low frequency clock and a low frequency counter for generating a first delay, and a second high frequency clock and a high frequency counter for generating a second delay. The system further includes a transmitter for transmitting the representative signals after a delay from the event made up by the sum of the first and the second delay. The second delay can be generated also by an analog device including for example a capacitor, and devices for charging the capacitor up to the reaching of a preset voltage at its ends. A wireless transmission system according to the invention is utilized in a checking system with a contact detecting probe, for transmitting a signal representative of contact with the piece to be checked.

Timing measurement for checking probes

A system for performing dimension checkings of mechanical pieces is provided including a contact detecting probe with wireless transmission, for example through a single radiofrequency two-way communication link, to and from a base station connected to an interface unit. The probe includes a logic unit and a memory unit in which reside the values of some operation parameters, for example the transmission frequency and/or the activation mode of the probe. The values of the operation parameters can be modified in a programming phase, according to a method that foresees the wireless transmission of control signals from a manually operated control device&#x2014;to the probe, for updating of the values among the selectable values of a sequence residing in the probe, and the acquisition of the current value.
