Optical Weldable Strain Gauge Rosette OR-W from HBM FiberSensing is highly suited for high strain applications in harsh environments, measuring strain in three different directions.
Optical Weldable Strain Gauge Rosette OR-W: Fiber Bragg Grating (FBG) based Sensor for Measuring Strain in Different Directions
The Optical Weldable Strain Gauge Rosette OR-W measures strain in three different directions and was specially developed to be spot welded on steel structures and materials exposed to harsh environments, such as the ones found in construction sites.
The optical rosettes are highly suitable for high strain measurements, experimental stress analysis and materials testing, withstanding adverse ambient conditions.
For the spot welding process the Heller c30 Impulse Welding Device is recommended (not available in the US).
- Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc)
- Electrical isolation
Safe operation in hazardous environments (e.g. potentially explosive environments, high voltage areas and intense electromagnetic fields)
- Stainless steel packaging
- Outstanding bending capability (6 micron core fiber)
Accurate results during 24/7 operation even on curved surfaces and under harsh environments
- Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctuations
Self-referenced: high quality measurements with long term stability
- Easy installation by simple spot welding method
Long service life with a permanent non-degradable attachment to the structure material
