Il est particuli\u00e8rement utilis\u00e9 pour analyser les d\u00e9formations dues \u00e0 la dilatation, au retrait et aux conditions de durcissement. Ce syst\u00e8me a \u00e9t\u00e9 d\u00e9velopp\u00e9 pour mesurer les variations dimensionnelles lin\u00e9aires des \u00e9chantillons de prisme ou de cylindre dans un environnement de laboratoire par rapport \u00e0 un cadre de r\u00e9f\u00e9rence pr\u00e9cis. Le comparateur de longueur de grand type d'YKMTEST est \u00e9quip\u00e9 d'un pont de mesure rigide en acier, de goujons de r\u00e9f\u00e9rence en acier inoxydable et d'un capteur de mesure num\u00e9rique \u00e0 haute r\u00e9solution. La mesure est effectu\u00e9e en mettant en contact l'\u00e9chantillon entre un point d'appui fixe sur le cadre de r\u00e9f\u00e9rence et la pointe de mesure mobile. Lorsque l'\u00e9chantillon est positionn\u00e9, l'unit\u00e9 de lecture num\u00e9rique de la pointe de mesure affiche la diff\u00e9rence de longueur \u00e0 un niveau microm\u00e9trique. Ce syst\u00e8me permet un suivi fiable des changements de longueur en fonction du temps, tels que le r\u00e9tr\u00e9cissement d\u00fb au s\u00e9chage ou l'expansion induite par les sulfates. L'appareil peut s'adapter \u00e0 diff\u00e9rentes longueurs d'\u00e9chantillons prismatiques et cylindriques. Sa large plage de mesure couvre une grande vari\u00e9t\u00e9 de tailles d'\u00e9chantillons. L'unit\u00e9 de lecture num\u00e9rique fournit des mesures avec une r\u00e9solution de 0,001 mm et affiche les valeurs instantan\u00e9es et diff\u00e9rentielles. L'unit\u00e9 de lecture dispose \u00e9galement de fonctions d'\u00e9talonnage et de mise \u00e0 z\u00e9ro faciles \u00e0 utiliser. Comme les points d'appui restent fixes pendant la mesure, les erreurs de mesure induites par l'op\u00e9rateur sont minimis\u00e9es.<\/p>","protected":false},"excerpt":{"rendered":"<p>Le comparateur de longueur de grand type avec unit\u00e9 de lecture est un appareil de laboratoire professionnel con\u00e7u pour mesurer avec une grande pr\u00e9cision les variations de longueur des \u00e9chantillons de b\u00e9ton, de mortier et de ciment en fonction du temps.
