Strain gauges for residual stress analysis: Ideal for ring core method and hole drilling method
Determining residual stresses in materials (e.g. during casting, welding and forming processes) becomes easy with HBM's special strain gauges.
The special strain gauges for residual stress analysis are available for a variety of commonly used methods in that field: in addition to the ring core method, there are more versions available for hole drilling (according to the integral method), and even for precise and safe high-speed drilling (in combination with the MTS3000 drilling device from our partner company Sint Technology).
For high-speed drilling, we also offer our patented six-wire strain gauges, which can compensate for non-centric boreholes, providing increased measurement accuracy.
- Supported residual stress measurement methods: Ring core method, integral hole-drilling, high-speed drilling
- Nominal resistance: 120 and 350 Ohm
- Measuring grid lengths: 1.5 to 5 mm
