Title (EN) MEASURING HEAD FOR INDICATING THE MOMENT OF CONTACT WITH THE SURFACE OF OBJECT
(FR) TETE DE MESURE INDIQUANT LE MOMENT DE CONTACT AVEC LA SURFACE D"UN OBJET
Abstract: front page image
(EN)A measuring head comprises a vibratory system mounted in a casing (1) and including a rod (4) with the ends of essentially different thickness, the thick end carrying a piezoelectric converter (7) and the thin end carrying a contact cap (15). The rod (4) is fixed in the casing (1) within the area of the nodal plaine of the vibratory system. The piezoelectric converter (7) is provided with current supplying elements (8, 10) connected to the output of the generator of electric oscillations, and with current collecting elements (9, 10) connected to an input of a phase-sensitive circuit, the other input of which is connected to the output of the generator. The measuring head can be used in devices for precise control of dimensions and reciprocal spacing of parts.
(FR)Une tete de mesure comprend un systeme vibratoire monte dans un boitier (1) et comprenant une tige (4) dont les extremites ont des epaisseurs differentes, l"extremite la plus epaisse portant un convertisseur piezoelectrique (7) et l"extremite la plus mince portant un capuchon de contact (15). La tige (4) est fixee dans le boitier (1) dans la zone nodale du systeme vibratoire. Le convertisseur piezoelectrique (7) est pourvu d"elements d"alimentation en courant (8, 10) connectes a la sortie du generateur d"oscillations electriques, et est pourvu d"elements collecteurs de courant (9, 10) connectes a une entree d"un circuit sensible aux phases, dont l"autre entree est connectee a la sortie du generateur. La tete de mesure peut etre utilisee dans des dispositifs de controle precis de dimension et d"ecartement entre des pieces.
