Abstract
An air dryer cartridge for reducing moisture of air supplied to an electronics housing has a cartridge housing containing a drying agent through which air is guided. A sensor unit of an optical measuring system is provided for determining the moisture content of the drying agent. The cartridge has a light-permeable casing surface section so that an optical signal emitted from the optical measuring system can pass through the casing surface section. In the method for determining a moisture content of the drying agent of the air dryer cartridge, an optical signal from a sending module is emitted onto or through the drying agent and received by a receiving module where a measured value is determined. The moisture content is determined by comparing the measured value with a data set of measured value-specific values for moisture contents or by a calculation rule for moisture content based on measured value.
