Abstract

Dispositivo elettro-ottico (1) per la rilevazione dell'interspazio (6) tra due pezzi metallici accostati atti ad essere saldati tra di loro in cui la superficie (5) dei pezzi viene esplorata ciclicamente da un fascio laser (13) incidente il dispositivo (1) comprende un diodo foto-rilevatore (30) che produce un segnale proporzionale all'intensità del fascio laser riflesso dalla superficie dei pezzi (5). Il dispositivo (1) comprende inoltre un circuito elaboratore (45) che campione in istanti successivi (t, t + 1) il segnale (V) generato dal diodo (30) e rileva quando tale segnale assume un valore minimo (Vm).[Fig.2]Electro-optical device (1) for the detection of the gap (6) between two metal pieces placed side by side which can be welded together where the surface (5) of the pieces is cyclically scanned by a laser beam (13) incident on the device (1) comprises a photo-detecting diode (30) which produces a signal proportional to the intensity of the laser beam reflected from the surface of the pieces (5). The device (1) further comprises a processor circuit (45) which samples the signal (V) generated by the diode (30) in successive instants (t, t + 1) and detects when this signal takes on a minimum value (Vm).
