Deformation sensor that enables measurement discrimination according to the direction of deformation

摘要

The deformation passive sensor (C2) comprises a system for detecting a change in distance between two points or areas of a structure, and first and second parts (1a, 1) configured to be fixed to said points or areas And b) the carrier (1). Said system is carried by a first part (1a) and a measurement assembly (13) operable in only one measurement direction to measure and store measurements associated with at least one deformation in the measurement direction. An actuating device (12), an intermediate assembly (15) having an actuating member (15c) for actuating the measuring assembly (13) and a second part (1b) facing the intermediate assembly (15) An actuation assembly (14) comprising a push part (14c) adapted to be displaced relative to the measurement assembly (13) only when the object moves in the measurement direction And (12).
