EM01: Mesure du couple \u00e0
l\u2019aiguille de seconde<\/h1>\n

MuT.03 – Exemple d\u2019application<\/h3>\n

La mesure du couple \u00e0 \u00e0 l\u2019aiguille des secondes (sans organe r\u00e9gulateur) permet de quantifier le fonctionnement du rouage d’un mouvement horloger. On retrouve les courbes de couple caract\u00e9ristiques de l\u2019engr\u00e8nement.<\/p>\n

Cette mesure a \u00e9t\u00e9 r\u00e9alis\u00e9e avec un MuT.03 A24W.1W (\u00b1240 uNm) et est pr\u00e9sent\u00e9e sans post-traitement. Le mouvement utilis\u00e9 est le ETA 2824 dont l’aiguille de seconde a \u00e9t\u00e9 entrain\u00e9 \u00e0 0.8 tr\/min.<\/p>\n
