ABSTRACT:
A weight sensor10having a simple structure and yet being capable of detecting load or pressure of an object to be measured in a short time and with high sensitivity and high precision. The sensor includes a first rotating shaft14vertically and rotatably supported on a stage12, a second rotating shaft18axially and coaxially connected to the first rotating shaft14with a magnetostrictive member16interposed therebetween for rotatably supporting an object20to be measured, and a pickup coil28for detecting changes in magnetic permeability or remnant magnetization of the magnetostrictive member16. Load or pressure of the object20is detected as the changes in magnetic permeability or remnant magnetization, which are caused by extension and contraction of the magnetostrictive member16.
