Description
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. 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 fibre 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 generates a better result.
