Fiber Optic Sensing System "FBI-Gauge"

With a single optical fiber, extensive strain and temperature measurements are achieved! Traditional spot measurements can now be performed as distributed measurements over lines and surfaces!

Are you facing challenges or requests in strain measurement and temperature measurement like these? "I can only measure parts of the object and want to measure a wider area easily." "I want to measure in narrow gaps that are hard to reach." "I want to conduct measurements in environments with electromagnetic fields or where open flames are prohibited." The "FBI-Gauge" is a sensing system for strain and temperature that utilizes optical fibers as sensors. It allows for continuous measurement along the optical fiber, enabling not only point measurements but also continuous and extensive line and surface measurements. Since it does not use a large number of strain gauges or thermocouples, installation costs and time can be significantly reduced. There are various measurement achievements, including torsion tests of vehicle bodies, temperature measurements on radiator thermometers, strain measurements in pressure tanks, and temperature measurements inside fuel cells. 【Features】 ■ Capable of line and surface measurements, not just point measurements ■ Significantly reduced sensor weight ■ Usable in electromagnetic environments and fire-prohibited areas ■ Can be attached with a flexible layout ■ Capable of diverse measurements of strain and temperature with a single sensor *For more details, please refer to the PDF document or feel free to contact us.
