At Polytec, fiber-optic measuring technology is split into two fields: “fiber-optic sensing technology” and “optical telecommunication / fiber-optic measuring devices”.
Fiber-Optic Sensing Technology:
Fiber-optic sensor systems use specific optical properties of materials – and often even the fiber itself – to measure physical variables such as temperature, strain or vibration. Extremely flexible solutions can be created in this regard: they range from the single-point measuring system, over individually defined spots along the fiber, to continuously measuring systems with a resolution of 1 mm across optical fibers that run for kilometers. A single fiber weighing just a few grams can therefore contain thousands of sensors and serve as a signal path at the same time. Because light is used as the transmission medium in the glass fiber, applications that remain off-limits to electrical sensor technology – such as in HF and microwave fields, high-voltage environments, potentially explosive atmospheres, chemically aggressive environments and much more besides – are indeed a possibility.
Optical Telecommunication / Fiber-Optic Measuring Devices:
Working in close cooperation with leading international manufacturers, Polytec offers you a wide range of measuring devices and components for optical data transmission technology. The products on offer cover the areas of development, quality assurance and production, as well as field use during installation and maintenance activities.
Applications and the measuring technology required for the same range from fiber-optic cables for telecommunication, over light source signal analysis, to sensor technology used for temperature, strain or vibration measurement, for example.
