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 have reached 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.
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.
Many tests and inspections are mandatory for approval of new railway vehicles. These include test runs with wheelsets enabling the forces between wheel and rail to be measured. At present, DB Systemtechnik in Minden, Germany, an...
Efficiently generating electric power without polluting the environment becomes increasingly important in times of high commodity prices and growing environmental awareness among consumers.
Modern lightweight materials are increasingly being used in aerospace applications and in other branches, such as traffic and construction engineering, mechanical engineering and the energy business. Fiber composite technology in...
Suitable sensor technology must be employed to detect the damage to wind turbine rotor blades early enough, and minimize the economic consequences. The sensors must be able to withstand tough ambient conditions and must...
Our comprehensive article provides basic knowledge on the topic: Everything you need to know about measurement using optical strain gauges: From technological background information through calibration of interrogators and...
When are electrical strain gauges adequate, when do you need to use optical strain gauges? This article describes the fundamental differences between the technologies and their implications for the respective fields of...
Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis.
Strain gauges can be integrated directly into a structure instead of being installed on the surface of a material. Read our extensive instructions on the topic to learn how to successfully integrate strain gauges into structures.
HBM patented optical strain gages utilize proven technology, and are easy to work with.
