FunctionThe air velocity sensor operates on the hot-wire anemom-eter principle. The sensor element is a specially designed thin film element which is heated. The cooling rate of the element, which depends on the air velocity, is meas-ured and is transformed by the built-in electronics to an analogue output signal proportional to the air speed. The signal is compensated for varying temperature. The very thin measuring element has the advantage of being highly resistant to contamination by dust etc.
