Abstract
The invention relates to an indirect measurement method of dewpoint or gas concentration and an apparatus suited for prediction of icing. The method is based on measuring the relative concentration of the gas directly and simultaneously measuring the temperature of the element (3) measuring the relative concentration of the gas. According to the invention, the temperature of the relative value measuring element (3) is shifted so as to bring the operation of the measuring element to a measurement range of maximally high sensitivity.
