Hi everyone. I am trying to make a hot-wire anemometer with this Pt100 thin film: http://uk.farnell.com/labfacility/dm-334/sensor-pt100-thin-film-2x10mm-cl/dp/8598525?Ntt=8598525 I want to heat it with constant current, and to measure wind speeds in range from 0 to 20 m/s. I need to simulate it without measurement first, and I'm stuck. How much current do i need to give it for this kind of measurement? It must me method with constant current because that is the point of my project.. Can you give me some ideas? Thanks!
