Fiber optic sensor for bidirectional air flow measurement in low-velocity process streams

This talk describes the development and evaluation of bi- directional fiber-optic based low airflow sensors for use in solvent containing elevated temperature manufacturing process environments. The sensors developed are based on Measureand Inc. cantilever beam optical fiber bend sensors. Customized paddles are added to match sensor output to the range of airflows under investigation. This talk discuses the sensor requirements, sensors' design, calibration, manufacturing process installation and testing process worthy prototypes in an elevated temperature solvent containing environment.
