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.

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: Disclosed is a system for measuring a gravity gradient tensor. The system comprises of: a gravity gradient sensor (40) with a pair of transversely arranged masses (41, 42) for use in a gravity gradiometer for measuring components of a gravity gradient tensor; a calibration sensor for sensing, at room temperature prior to cryogenic operation of the gravity gradiometer, whether one of the pair of masses associated with the calibration sensor is balanced; and an adjusting mechanism for adjusting the balance of the masses at room temperature prior to cryogenic operation of the gravity gradiometer. The calibration sensor comprises a resonant circuit having an inductor, and a capacitor which has a first plate formed by a surface of one of the masses and a second plate spaced from that surface of one of the masses; and an oscillator for receiving a signal from the resonant circuit and for producing an output signal indicative of the spacing between the first plate and the second plate. In use the calibration sensor produces a signal indicative of the balance of the one of the pair of masses associated with the calibration sensor.
