ABSTRACT:
An electric hygrometer wherein a body of viscous hygroscopic electrolyte is supported exclusively by two or more spaced-apart carriers so that the electrolyte contacts the gaseous medium whose relative humidity requires determination and is in conductive contact with two conductors. The impedance between the conductors varies with relative humidity of the medium. The carriers may consist of conductive and/or insulating material; in each instance, the carriers may constitute spheres, straight wires, U-shaped or V-shaped wires, loops, open or closed rings or other configurations. If the electrolyte is supported by two carriers only and the carriers consist of conductive material, each carrier is integral with one of the conductors and those portions of the carriers which contact the electrolyte constitute two electrodes which are conductively connected with the respective conductors. The configuration of the electrolyte between the carriers depends on the shape of carriers, on the distance between the carriers and/or the viscosity of electrolyte.
