  • Patent number: 6926439
    Abstract: A dew point hygrometer for determining the dew point of a gas in which a displaceable transparent film is in contact with the gas and forms a condensation surface. The film is placed on a temperature control device controlling its temperature and an optic fiber, emits light on the film and reflected light is detected in another optic fiber, the two optical fibers being positioned at an angle with respect to the film. Condensation formed on the film changes the light transmitted by the film which is periodically displaced so that a new uncontaminated regions are exposed to the light.

  • Patent number: 6575621
    Abstract: The invention concerns dew point hygrometers based on condensation of dew on ends of optical fibers, or on surfaces of an optical prism. The invention also concerns a dew sensor for determining the natural dew condensation by optical means and a dew sensor capable of detecting dew by detecting a change in capacitance.
