Abstract: Se describe un gradiometro de gravedad que tiene un sensor en la forma de barras (41 y 42) que van apoyadas en un soporte (5) que consta de una primera seccion de soporte (10) y una segunda seccion de soporte (20). Una primera banda continua flexional (33) acopla sobre un eje la primera y segunda secciones de soporte alrededor de un primer eje. El segundo soporte tiene una primera parte (25), una segunda parte (26) y una tercer parte (27). Las partes (25 y 26) van conectadas por una segunda banda continua flexional (37) y las partes (26 y 27) van conectadas por una tercera banda continua flexional (35). Las barras (41 y 42) estan localizadas en carcasas (45 y 47) y forman una estructura monolitica con las carcasas (45 y 47), respectivamente. Las carcasas (45 y 47) van conectadas a lados opuestos de la segunda seccion de soporte (20). Las barras (41 y 42) van conectadas a sus respectivas carcasas por bandas continuas flexionales (59).

Abstract: A gravity gradiometer is disclosed which has a sensor in the form of bars (41 and 42) which are supported on a mounting (5) which has a first mount section (10) and a second mount section (20). A first flexure web (33) pivotally couples the first and second mount sections about a first axis. The second mount has a first part (25), a second part (26) and a third part (27). The parts (25 and 26) are connected by a second flexure web (37) and the parts (26 and 27) are connected by a third flexure web (35). The bars (41 and 42) are located in housings (45 and 47) and form a monolithic structure with the housings (45 and 47) respectively. The housings (45 and 47) are connected to opposite sides of the second mount section 20. The bars (41 and 42) are connected to their respective housings by flexure webs (59). Transducers (71) are located in proximity to the bars for detecting movement of the bars to in turn enable the gravitational gradient tensor to be measured.
