Optical Strain Gauge Rosette OR: Fiber Bragg Grating (FBG) based Sensor for Measuring Strain in Different Directions

The Optical Strain Gauge Rosette OR is one of the smallest strain gauge rosettes in the world, tolerating extreme loads and high strain levels.

Unlike linear optical strain gauges, the OR comprises three strain gauges – i.e., measures strain in three directions – allowing the measurement of strain in 0º, 60º and 120º directions.

Passive

  • Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc)
  • Electrical isolation

Accurate results in adverse conditions (e.g. potentially explosive environments, high voltage areas and intense electromagnetic fields)

Robust

  • Patented sensor design
  • Outstanding bending capability (6 micron core fiber)
  • Plastic packaging

High quality measurements during 24/7 operation even on curved surfaces.

Resistant

  • Withstanding 10 million load cycles at ±5.000 µm/m alternating strain

No mechanical failure: high resistance to fatigue under high alternating loads

Convenient

  • Easy handling and simple installation of multiple gauges in a single optical fiber

Benefiting from both optical sensor technology and a wide range of accessories for electrical strain gauges
