DIGITAL GRAVIMETER FOR ABSOLUTE MEASUREMENT OF ACCELERATION OF GRAVITY

摘要

The invention relates to means for gravimetric measurements. Digital gravimeter for absolute measurements of acceleration of force of gravity includes arranged in sequence indicator of displacement, transformer, computing system and system of indication. Transformer is connected to computing system through matching device that consists of connected in series control and high-rate amplifiers, with its output connected to high-speed analog transformer (SAP) connected top clock for control of transformer that consists of connected to each other micro-circuit for memory control and processor for collection and processing of data connected to permanent memory device, at that output of processor for data collection and processing is connected to indicator and controller, output of the last one is connected to blocks of software provision of information processing outputs of which are connected to block for evaluation of spatial-time parameters of motion of indicator of displacements of ballistic gravimeter connected to block for determination of acceleration of gravity. The invention decreases error of measurement.
