Abstract

L'invention concerne un détecteur de chocs à gouttelette suspendue. Ce détecteur comprend une gouttelette de liquide 11 suspendue au moyen d'un élément de retenue 13 qui l'empêche de s'échapper, sauf lorsqu'il est soumis à une accélération dépassant une valeur prédeterminée, auquel cas une partie au moins de la gouttelette 11 s'échappe de l'élément de retenue 13. L'invention est utilisée pour détecter les chocs auxquels sont soumis des appareillages délicats.
