FS62 Optical Strain Sensors from HBM FiberSensing are particularly suited for structural health monitoring in large structures and testing in laboratory applications.
FS62 Optical Strain Sensors: High Performance Fiber Bragg Grating (FBG) based Sensors
FS62 Optical Strain Sensors are designed to be bonded to surfaces and materials, spot welded to structures and components, attached or directly cast into concrete wet mix.
Their small size and weight makes them the ideal choice for hard-to-reach locations and measuring points, remote sites and spots that are difficult to access.
Particularly suited for structural health monitoring in large structures (SHM), these sensors match perfectly the requirements of strain measuring in several indoor or outdoor applications.
- Inherent immunity to all electromagnetic effects (EMI, RFI, sparks, etc)
- Electrical isolation
Safe operation in hazardous environments (e.g. potentially explosive atmospheres, high voltage areas and intense electromagnetic fields)
- Connection of a large number of sensors to a single optical fiber
- Multipoint measurements
Reduction of installation complexity: much simpler sensing networks and cabling
- Based on the measurement of an absolute parameter - the Bragg wavelength - independent of power fluctuations
Self-referenced: high quality measurements with long term stability and low losses even in remote sensing
- Innovative sensor design
- Polyimide, stainless steel or composite packaging
- IP68 for surface and embedded sensors
Enhanced lifetime: even under adverse conditions (humidity, salt, EMF, pressure…)
Special FS62 Athermal Strain Sensor
- Athermal operation ensured by mechanical packaging, meaning that strain measurements are performed with only one FBG and without considering the effect of temperature on the sensor.
