FORCE MEASURING DEVICE Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: device has magnetostriction converter, which is made in form of a case to which resilient magnetic core is attached, which is made of magnetostriction material. The core is loaded to form torsion deformation. Ac meter is connected electrically with ends of flexible core of the converter. Ac power supply is made in form of current source. Terminals of current supply are connected with ends of resilient core as well. Resilient core of magnetostriction converter is made in form of a flat double-entry spiral. Internal ends of the spiral are attached to the case, insulated one against another and connected electrically with ac voltage meter. External ends are connected electrically and mechanically together. Converter core may also be made in form of a flat double-entry spiral, which has external ends attached to the case and insulated one against another, as well as connected electrically with ac voltage meter. Internal ends are connected together by means of electro-conducting ring which is aligned with the spiral. Spirals may be filled with elastic dielectric material along the total surface between external and internal ends of the spiral. EFFECT: improved efficiency of operation. 4 cl, 7 dwg
