Abstract
A system for detecting linear dimensions of mechanical workpieces includes a checking probe with detecting devices, a power supply and a remote transceiver unit. A stationary transceiver unit is located at a distance from the probe, and is adapted for wireless receiving and transmitting to the remote transceiver unit signals, for example, coded optical signals. The stationary unit transmits activation and/or deactivation signals to the probe for controlling the full power supply of the probe circuits, and/or the return to a “stand-by” power state. The remote transceiver unit includes devices adapted for achieving an automatic sensitivity control and other attenuation devices for preventing unwanted consumption of the probe battery energy due to noise signals. Such noise signals could come from fluorescent lamps, for example, causing improper activation and deactivation of the probe circuits.
