Accurate measurement of displacement
Fiber optic sensors use non-contact optical measurement to determine distance, position, and movement with high precision. These sensors are based on the principle of reflection. A fiber optic cable transmits light to a target surface and measures the intensity of the reflected light to calculate distance or displacement with high precision.
Because the measuring head itself contains no electronics, these sensors are ideally suited for extreme conditions such as high temperatures, electromagnetic fields, vacuum applications, and high-radiation environments. The electronics are located remotely from the object being measured, ensuring maximum robustness and installation flexibility.
Fiber optic sensors measure down to micrometer levels and offer fast response, high reproducibility, and a long service life. They are available in various configurations, including models with single or multiple fiber channels and with options for dynamic measurements of vibration or rapidly changing positions.
Fiber optic sensors are used worldwide in demanding environments where traditional measurement systems fall short. Thanks to their non-contact measuring principle and robust fiber optic technology, they offer a reliable solution for precise distance and motion measurements, even under extreme conditions.
Typical applications include:
Drive technology and rotor dynamics
Measurements of shaft displacement, alignment and vibration in rotating machines such as turbines, pumps and engines.
Semiconductor and chip production
Highly accurate distance measurements for positioning and quality control in vacuum environments and clean rooms.
Aerospace and defense
Vibration measurements and material displacement during test programs for jet engines, rockets or other aerospace components.
Medical technology
Position measurement of precision components in medical analysis or treatment equipment.
Materials testing and R&D
Real-time monitoring of deformation, bending or strain in materials during test setups or cyclic loading tests.
Energy and nuclear technology
Safe measurement in environments with high temperatures, electromagnetic radiation or limited accessibility.
Industrial automation
Feedback systems for precise motion control in assembly lines or inspection machines.
Thanks to the ability to remotely mount the electronics, these sensors function seamlessly in environments where heat, vibration, or electromagnetic interference would disrupt the operation of conventional sensors.
