The Spider-80SG can acquire data from a strain gage or a wide range of measurement quantities. (Strain gauges) Photoelectrical. For more detail, please refer to the AI Strain … Strain gauges in their infancy were metal wires supported by a frame. To measure strain, virtual strain gauges are placed at each edge of a triangulated measurement grid. Hardware and Software to Measure Strain. Axial and radial deformation measured directly on the triaxial test specimen: Removes bedding errors or “end effects”. Fundamentals of Strain Measurement Definition of Strain: Strain is a measure of change in length - it is a relative number. Board Flexure 8 Intel® Manufacturing Enabling Guide March 2016 Strain can be calculated by: ε = ΔL / L1 This value is dimensionless (the units of length cancel out). Strainoptics is the world’s foremost manufacturer of polarimeters and polariscopes, non-destructive stress measurement instruments for the glass and plastics industries. 4-wire strain measurement method. the input impedance of any instrument applied across the output terminals of the bridge circuit is effectively infinite. As a result, benchmark data accumulated for a given instrument tend to be super-seded by better performances as new detectors and config-urations that are more optimized are developed. A variety of instruments for use in strain related applications, from dataloggers, bridges and amplifiers to full systems. Since the measurement of strain involves the deformation of metal, the strain material need not be limited to being a wire. Data Acquisition Systems & Instruments.
