ABSTRACT:
An apparatus and method for continuously metering the vapor pressure of a gaseous component of a material within a gaseous mixture utilizing a saturation vapor pressure sensor having a linear dimension changeable with respect to changes in the saturation vapor pressure of the material, a relative humidity sensor having a linear dimension changeable with respect to changes in the relative humidity of said gaseous mixture, and a means to contrast the linear dimension of one of said sensors to the linear dimension of the other, the resultant value representing the vapor pressure of said material.
