Title:
FOUR POINT SUPPORT MEASURING DEVICE USING STRAIN GAUGE WEIGHTING INSTRUMENT
Document Type and Number:
Japanese Patent JPS5832126
Kind Code:
A
Abstract:
PURPOSE: To facilitate maintenance control over a measuring instrument by composing a Wheatstone bridge of a strain gauge for sensing compressing strain and a strain gauge for temperature compensation.
CONSTITUTION: A load table is supported at four points by four strain gauge weighting instruments AWD each composed of an active gauge as a strain gauge for sensing compressing strain and a dummy gauge as a strain gauge for temperature compensation. The active gauges and dummy gauges of the strain gauge weighting instruments AWD constitute a Wheatstone bridge, whose output is supplied to an indicator 13 through an amplifying circuit and an arithmetic circuit 12.
