The new 2071A Fiber Segment Interferometry (FSI) optical strain sensor array from Kistler is a non-invasive fiber optic sensing solution for demanding applications and harsh test environments. It requires minimal space, is lightweight and immune to electromechanical interference, and it can be customized.
Measurements become especially challenging when strain changes are both very small and highly dynamic. In vibration analysis, impact testing and acoustic emission monitoring, the measurement system must capture fast events without adding mass or stiffness that could influence the test structure. This combination of measurement speed, precision and minimal sensor influence is essential in applications ranging from shock tube and passive safety testing to battery development and structural health monitoring.
The 2071A FSI strain sensor array features:
- FSI, a measurement technology that works by detecting phase shifts in reflected light in each of the sensor segments.
- Customizable with up to 22 segments per sensor and segment lengths between 8 mm and 200 mm.
- A resolution down to 20 nε.
- A dynamic range of up to 10,000 µε.
- Sampling rates up to 410 kHz.
- A sensing section diameter of only 155 µm.
- A temperature range from –55°C to 300°C.
The measuring chain is completed with the 2549A FSI Interrogator, the data acquisition system including the Kistler Cockpit software. Overall, this fiber optic sensing solution supports sampling rates of up to 410 kHz, allowing even very fast transient strain events to be captured with high fidelity.
