Features
Shear/Torque Strain Gages are for measuring shear strain and torque, typical applications are for measurements on torsion bars and determining shear stresses in shear beam load cells.
M Series strain gauges have been specially developed for high resistance to alternating loads at increased strain levels and high temperatures up to 300°C (572°F). They are foil strain gauges with measuring grids made of a special nickel-chromium alloy. OMEGA/HBM offer this special strain gauge with various geometries, measuring grid lengths and temperature response matching.
New materials offering high strength such as fiber composites pose a major challenge for strain gauges used for measurements specifically when pushing components to their mechanical limit of performance. Situations may arise where a strain gauge subjected to alternating loads at increased load levels is weakened and fails earlier than the component under test. The M Series has been specially developed for high resistance to alternating loads and allows for testing of materials featuring high strength.
All M Series strain gauge types are available with different measuring grid lengths:
• 1.5 mm: where space is a constraint or when highly selective measurement results are required
• 3 mm: for inhomogeneous materials and where space is a requirement or not
• 6 mm: for inhomogeneous materials and where space is not a requirement
The right measuring grid length: The measuring grid length depends on the aim of measurement, since the result of a measurement with strain gauges will be determined as the average of strains. In general, measuring grid lengths of 3 to 6 mm (0.06 to 0.24') generates a better result.
Long measuring grids are recommended where there is an inhomogeneous material such as concrete or wood. A long strain gauge will bridge the inhomogeneity of the work piece and return the strain underneath the measuring grid as the measurement result.
Short measuring grids are suitable for detecting a local strain state. Therefore, they are suitable for determining strain gradients, the maximum point of notch stresses and similar stresses.
