Abstract

L'invention décrit un dispositif détecteur permettant de détecter des paramètres de transport représentatifs de ceux concernant un échantillon pendant un transport. L'échantillon est stocké dans un récipient. Le dispositif détecteur contient un boîtier dont la configuration correspond globalement à la configuration du récipient, une partie durcie de substrat, formée à partir d'un matériau de substrat, et un ensemble détecteur comprenant au moins un détecteur permettant de détecter au moins un paramètre de transport (par ex. l'accélération, l'orientation, la température, etc.). L'ensemble détecteur est fixé à l'intérieur du boîtier par la partie durcie de substrat. Un poids du dispositif avoisine éventuellement un poids combiné du récipient et de l'échantillon qui y est stocké. Le poids du dispositif détecteur peut être réglé. Lorsque le dispositif est positionné à proximité du récipient pendant le transport, lesdits paramètres de transport détectés par lesdits détecteurs sont analogues auxdits paramètres de transport concernant le récipient.
