HBM FiberSensing Optical Solutions

Optical Measurement Solutions based on FBG Sensors

Bringing light to measurement

Gain from the many new possibilities provided by optical sensor technology based on Fiber Bragg Gratings - and HBM's proven reliability.

HBM FiberSensing is proud of having addressed hundreds of different monitoring projects around the world and delivered thousands of sensors and measurement units throughout the years.

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...

A single fiber can handle multiple measurements. With optical sensors from HBM you benefit from reduced wiring requirements. Several optical sensors 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 FBG sensors 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.
