Abstract:
A sensor for use in a resistive measurement apparatus for measuring resistance of an aqueous fibrous solution comprising:a first electrode means having a first associated response function to first and second properties of said aqueous fibrous solution wherein the first property is the water weight of the aqueous fibrous solution and the second property is the resistance or conductivity of the aqueous fibrous solution and having a first sensitivity to said first and said second properties, said first electrode means detecting changes in resistance to obtain a first resistive measurement corresponding to changes in said first and said second properties;a second electrode means having a second associated response function to said first and second properties of said aqueous fibrous solution and having a second sensitivity to said first and said second properties, said second electrode means detecting changes in resistance to obtain a second resistive measurement corresponding to changes in said first and said second properties;wherein a measurement of said first property is obtained by arithmetically solving said first and said second response functions using said first and said second measurements along with predetermined characterization data.
