DESCRIPTION
BA-OFS2 multi-functional surface mounted fiber grating strain sensor is a surface mounted strain measurement sensor developed for the needs of detection, evaluation and online monitoring of bridges and building structures. It is designed with 70mm gauge distance, taking into account the requirements of gauge distance for concrete and steel structure surface strain measurement.
This product has fixed and reusable bases, which meet the requirements of long-term monitoring for single use and short-term monitoring for multiple reuse.
Application Scenario
Bridge completion inspection, structural static and dynamic load testing;
Long term safety monitoring of bridges and building structures;
Destructive tests for quality inspection of concrete and steel;
Measurement of surface strain of asphalt concrete and polymer materials;
Strain measurement of aviation aluminum, titanium alloy, carbon fiber, etc;
Strain testing of helicopter propeller blades;
Aircraft static load testing and dynamic load testing;
Wind turbine blade strain monitoring.
