METHOD AND APPARATUS FOR DETERMINING THE SATURATION OF A DRYING CARTRIDGE

摘要

A method and apparatus for determining the degree of water saturation of the hygroscopic desiccant of a drying cartridge as a function of the variation in the dielectric constant of the hygroscopic material. The invention takes the form of a tubular capacitor disposed in the mass of hygroscopic desiccant material proximate the outlet of the drying cartridge, and of appropriate circuits for measuring the level of saturation of the desiccant material and for operating alarm and safety devices.
