Abstract
Possible ways of using a transistor as an anemometer are examined to discover desirable properties, suitable for use in a battery-operated instrument. Two modes of operation are described: constant power and constant temperature rise above ambient. Bead transistors allow convenient operation at 30 mW with straightforward ambient temperature compensation. To verify what constitutes an adequate thermal model, a detailed analysis is given for a particular transistor and shown to be in agreement with experiment.
