CONT

Wind speed within the canopy was measured using thermo-electric anemometers ...

CONT

The principle of thermoelectric anemometers is based on the flow-induced cooling of a heated sensor region. The resulting temperature differences are transduced into electrical voltages using the Seebeck effect.

CONT

A thermoelectric anemometer which is especially useful for measuring very low velocities of air flow, (0.01 m/s). In addition to air speed and temperature, it is also capable of measuring humidity (when used with HygroAir probe 950272).

CONT

Les anémomètres thermiques utilisant la modification des échanges thermiques d'un corps chauffé par l'air en mouvement : anémomètre à fil chaud, anémomètre thermoélectrique. [...] Anémomètre thermoélectrique. Ces anémomètres comportent un fil ou une sphère (préférable car non directionnelle) chauffés à puissance constante et un thermocouple qui mesure l'écart de température entre le corps chauffé et un corps identique placé dans l'air; très sensible aux faibles vitesses du vent, ils ont comme inconvénient leur inertie et leur manque de précision.
