New horizons for your measurements... The optical measurement chain from HBM
Gain from the many new possibilities provided by optical sensor technology - and HBM's proven reliability.
Determine stress in components and in environments where conventional technologies havereached their limits.
Reliably and safely test innovative materials with high levels of strain or high numbers of load cycles, high electromagnetic stress or in highly explosive environments.
Measurement using light... see how it works!
Measuring with light: A whole bundle of benefits
- Reduce your installation costs...
...because a single fiber can handle multiple measurements.
With optical strain gages from HBM you benefit from reduced wiring requirements. Several optical strain gages can be used on a single fiber. The optical measurement chain is individually adapted to suit your requirements.
- Get high-precision test results...
...even in difficult environments and materials
Optical strain gages enable you to test the fatigue strength of your components. Stress testing can be conducted even in materials with high levels of strain, and with high numbers of load cycles. You get consistent and accurate test results even in adverse ambient conditions, for example, in high-voltage systems.
- Acquire reliable data...
... whatever the distance between your optical strain gages and the measurement system.
The effects of distance and cable length on the test result can be neglected with optical strain gages. Even if your data acquisition system is located many hundred meters from the measuring points, the use of optical sensor technology will not negatively affect the quality of your test results.
