I work for a research group at my university. We are considering the use of a hot-film sensor array to characterize flow over our a portion of an airfoil in the wind tunnel. We are looking for something like the http://www.taosystem.com/products/senflex/" [Broken] sensors offered by Tao Systems. I tried searching for more options but Tao Systems was the only company I could find who offered something like this. Does anyone know of any other companies who sell something similar to the Senflex sensors?
