Strain measurement with reduced time and material - using rosette strain gauges with associated amplifying evaluation and output units

摘要

Rosette strain gauges (6-8) are coupled with associated amplifier and output units. The amplified output signals of the strain gauges in each rosette (1-4) are converted by an evaluation unit (26) supplied by the amplifier unit (9) into values for the main normal strain, the main strain direction and the compensation strain. The values are fed to the output units (27-29). USE - For building structures having forces acting in several axes.
