Strain Gauges for Special Applications
Residual Stress Strain Gauges
HBM offers you strain gauges for analysis of residual stress and for the ring-core method as well as the hole drilling method.
HBM crack propagation gauges are used to determine crack propagation in a component. HBM offers three different types.
The LS31 is a weldable strain gauge (SG) for measurements at elevated temperatures on weldable components and for use
The increased use of fiber composites and the systematic optimization of components presuppose a precise knowledge of the load situation.
Use of LD20 is recommended wherever high strain or compression occurs (>5 %). The SG has a maximum elongation of +/- 100,000 µm/m (+/-10 %).
