摘要 |
A saturation level of moisture and/ or other contaminants is determined in a desiccant material by determining an electrical parameter across the desiccant material. An air dryer includes a housing, a desiccant in the housing, and an electrical contact in the desiccant. A level of at least one of moisture and other contaminants is determined as a function of a n electrical parameter between two electrical contacts of dissimilar materials that electrically contact the desiccant. Alternatively, the level of at least one of moisture and other contaminants is determined as a function of an amount of the reflected light received by the optical sensor from the desiccant.
