- Figure 1. This graph logs power dissipated vs air speed of a TO92 held at a constant 31 °C above ambient. PW = 31/ZT
- Figure 2. This circuit implements a phantom-powered Darlington anemometer with a 40-140 mA current mode output. Adjust R10 to calibrate 40 mA (zero fpm), and R11 to calibrate 140 mA (250 fpm). The adjustments interact so some iteration may be necessary. Sorry 'bout
- Figure 3. This graph logs Q1 power dissipation vs collector current
- Figure 4. This graph logs anemometer output vs airspeed. FPM = 2.5(IOUT - 40 mA)
