Hi guys, I am calibrating my hot wire anemometer in the wind tunnel, through the use of an amplifier. Now, as I am calibrating, the voltage is set to a maximum of 9V since if exceeds 10V, it damages the card data reader. My question is that: for hot wires, when the velocity increases, the voltage should too. but the reading I got were of a decreasing voltage as the speed of the wind tunnel was increased.
does anyone has an explanation for that? thanks
