Method and apparatus for measuring relative humidity of a mixture

摘要

A method and apparatus for measuring relative humidity of a mixture that provides a quick response time for thermal lag while affording protection to fragile sensors. In one aspect, the invention is a method for calculating the relative humidity of a mixture comprising measuring a chamber relative humidity (RHC) within a chamber enclosing an humidity sensor; measuring a first temperature (TC) within the chamber; measuring a second temperature (TA) separate from said chamber, said second temperature being the temperature of the mixture; and calculating the mixture relative humidity (RHA) based on the chamber relative humidity, a first value representing the first temperature and a second value representing the second temperature.
