Magnetostrictive fluid-pressure sensor

摘要

A magnetostrictive fluid-pressure sensor includes annular inner and outer cylinders, a first connector, annular second and third connectors, and first and second coils. The inner cylinder surrounds a fluid-receiving bore. At least one of the cylinders is a magnetostrictive cylinder. The first connector connects the first ends of the cylinders and has a first portion extending radially inward of the inner cylinder. The second connector connects the second ends of the cylinders and defines a fluid inlet. The third connector connects the cylinders and is positioned longitudinally between the first and second connectors. The first coil is positioned radially between the inner and outer cylinders and longitudinally between the first and third connectors. The second coil is positioned radially between the inner and outer cylinders and longitudinally between the second and third connectors.
