Zusammenfassung:	A coating thickness measuring device is esp. for dielectric, non-magnetic, electrically conducting materials etc. It is applicable to plate coating regulation in metallurgy and industrial machine mfr., e.g. for corrosion protection. It ensures uniform sensitivity over all measurement regions, eliminates region boundary null drift, and guarantees a high degree of measurement accuracy. A thickness detector electrical output is fed to a circuit converting it into an electrical signal proportional to thickness. Thickness detector output signals are fed to a peak detector driving a subtractor and a measurement range switch. A reference voltage is connected to the other switch input and the switch output drives the other subtractor input. The subtractor and range switch drive a sensitivity correction circuit. The thickness proportional signal is produced by a summer adding the range switch output and the correction circuit output. CE DISPOSITIF COMPORTE UN DETECTEUR 2 D'EPAISSEUR RELIE A UN CIRCUIT 3 DE CONVERSION DU SIGNAL DE SORTIE DU DETECTEUR D'EPAISSEUR EN UN SIGNAL PROPORTIONNEL A L'EPAISSEUR DU REVETEMENT. L'ENTREE DU CIRCUIT DE CONVERSION EST UNE ENTREE D'UN DETECTEUR DE CRETE 4 DONT LA SORTIE EST RELIEE AUX ENTREES 5, 7 RESPECTIVEMENT D'UN BLOC 6 DE COMMUTATION AUTOMATIQUE DE GAMMES DE MESURE ET D'UN BLOC DE SOUSTRACTION 8. L'ENTREE 9 DU BLOC 6 EST BRANCHEE SUR LA SORTIE D'UN BLOC 10 DE FORMATION DE LA TENSION DE REFERENCE, TANDIS QUE LA SORTIE 11 EST RELIEE A L'ENTREE DU BLOC 8. LA SORTIE 16 DU BLOC 8 EST BRANCHEE A L'ENTREE D'UN BLOC 13 DE CORRECTION DE LA SENSIBILITE DE MESURE DONT L'AUTRE ENTREE EST RELIEE A LA SORTIE 12 DU BLOC 6. LA SORTIE 17 DU BLOC 13 EST BRANCHEE A L'ENTREE D'UN BLOC D'ADDITION 15, DONT L'AUTRE ENTREE EST BRANCHEE SUR LA SORTIE 14 DU BLOC 6. LA SORTIE 18 DU BLOC D'ADDITION 15 SERT DE SORTIE DU CIRCUIT DE CONVERSION ET EST BRANCHEE SUR UN DISPOSITIF ENREGISTREUR 19.
