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.
Claims9
A device for continuously measuring the vapor pressure of the vapor phase of a material within a gaseous mixture comprising:
- a. saturation vapor pressure sensor including a closed container of at least two phases of the material, one of which is the vapor phase in the predetermined gaseous mixture, a linear dimension of said container being changeable with respect to changes in the saturation vapor pressure of the material;
- b. relative humidity sensor within the predetermined gaseous mixture, a linear dimension of said sensor changeable with respect to changes in the relative humidity of said gaseous mixture;
- and
- c. means to contrast the linear dimension of one of said sensors to the linear dimension of said other sensor, the resultant value representing the vapor pressure of the material.
A method of continuously measuring the vapor pressure of the vapor phase of a material within a gaseous mixture comprising the steps of:
- a. translating the saturation vapor pressure of the material into a linear dimension;
- b. translating the relative humidity of the material into a linear dimension;
- and
- c. contrasting said linear dimensions, the resultant value representing the vapor pressure of the material.
