System for detecting linear dimensions of mechanical workpieces, with wireless signal transmission units

A system for detecting linear dimensions of a workpiece comprising:

• a checking probe with detecting devices;
• a power supply connected to the checking probe;
• a remote transceiver unit, integral with the probe, connected to the detecting devices and to the power supply, and adapted for wireless transmission of signals indicative of the state of the probe;
• and
• a stationary transceiver unit, adapted for wireless transmission of activation signals to said remote transceiver unit,
• the remote transceiver unit comprising receiving devices adapted for receiving the wireless transmitted signals, a processing section connected to the receiving devices and to the power supply and adapted for generating an enable signal, a switching unit connected to the processing section and to the power supply, and additional sections connected to the switching unit, the switching unit being adapted for receiving the enable signal and, on the basis of this signal, controlling the power supply of at least one of said additional sections, wherein the processing section includes attenuation devices adapted for inhibiting the generation of the enable signal based on attributes of the signals that the receiving devices have received.
