M Series Strain Gauges: For Stress Analysis of Materials with High Fatigue Strength

M series strain gauges are foil strain gauges for stress analysis of materials with high fatigue strength such as fiber composites. They can also be used in product development, for example in the aerospace or sporting goods industries. 

In addition, M series strain gauges offer a very large temperature range. Due to their excellent fatigue life, M series strain gauges enable measurements to be repeated extremely frequently, also in case of high strain. Properties such as different geometries, resistance values, and measuring grid lengths can be combined to configure the ideal strain gauge—over 36 preferential strain gauges are available for immediate delivery.

  • Temperature range: -200 to +300 °C
  • Load cycles: Up to 10 million at +/- 2000 µm/m fatigue loading
  • Measuring grid lengths: 1.5 to 6 millimeters
