GRAVIMETRE

摘要

FIELD: instrument making. ^ SUBSTANCE: gravimetre consists of massive temperature-controlled unit on horizontal hard bottom of which there located is a drop of partially wetting liquid, which is fixed with a thin metal pin. Reading of wetted spot radius value which is supplied to the input of calculation device calculating the gravitational acceleration value as per radius value is taken with measurement optic system. ^ EFFECT: gravimetre has simple design, it is easy to operate and it has small dimensions and weight. ^ 1 dwg
