According to the characteristic that the resonant frequency of the resonant cavity shifts with the change of the air permittivity, this paper presents the frequency measurement system based on the microwave cavity wetness measurement system and realizes the accurate measurement of the steam wetness. A new method of frequency measurement is introduced, which is the combination of multi-cycle synchronization...
A wet steam humidity measurement method based on microwave differential technique is presented in this paper. The calculation model of equivalent dielectric constant of wet steam at different temperature and pressure is established. The measurement system is designed, which substitutes additional instrument for integrated module and uses two resonators to counteract system error. The principle of...
