High-Performance Optical Fiber Sensors

HBM FiberSensing offers two lines of optical strain gauges and sensors based on Fiber Bragg Grating (FBG) technology:

  • The FS Line includes strain sensors in different formats and is most suited for large sensing networks. This line ensures connectivity along several kilometers of fiber without compromising the sensors signals.
  • The OP Line comprises strain sensors for high strain applications due to their outstanding resistance. With intrinsic bending capability, the strain gauges from the OP Line are available as linear gauges or strain rosettes. 
FS62
Optical strain sensors based on Fiber Bragg Grating technology for structural health monitoring and testing in laboratory applications.
K-OP
Optical strain gauges with outstanding bending capability and high performance coatings for high strain measurements.
K-OP-A
Optical-armored strain gauges and rosettes suitable for high strain measurements in extremely harsh environments.
OptiMet
Single optical fibers with multiple fiber Bragg gratings with different protection coatings for multipoint measurement of strain in demanding applications.
