Hot Wire Anemometer
A triple point hot wire anemometer. Anemometers detect changes in fluid flow by convection from the hot wire at their apex. As the surrounding fluid velocity increases, the rate of convection heat loss increases and the wire cools. This temperature change is sensed as a change in wire resistance. The sensors are 400µm tall and have been produced as tall as 1000µm. The hotwire is made of platinum and nickel and the legs are made of permalloy to facilitate magnetic assembly.
