Gravity Gradiometer to measure components of the gravity gradient tensor which includes at least one sensor for Mass Movement in response to Gravity gradient and a transdermalUctor to measure the Movement of the Mass sensor.

摘要

A gravity gradiometer is described which comprises a pair of sensor bars arranged in housings. Transducers are arranged adjacent the bars for measuring movement of the bars in response to the gravity gradient tensor. At least one of the transducers has a sensing coil and a capacitor plate having a concentric arrangement with the sensing coil for providing one plate of a capacitor used in a balancing circuit for measuring the balance of the sensor mass.
