Determining relative moisture of air and gases under changing pressure and temperature ratios comprises acquiring moisture signals using drift-free sensor, and releasing within common temperature region of sensors

摘要

Determining the relative moisture of air and gases under changing pressure and temperature ratios obtained by a first sensor comprises acquiring moisture signals using a drift-free sensor, and releasing within the common temperature region of the sensors as measuring data. The first sensor is calibrated using the moisture signals of the drift-free sensor. An independent claim is also included for a device for determining the relative moisture of air and gases under changing pressure and temperature ratios comprising a sensor for feeding digital signals corresponding to the acquired moisture to a data processing unit, and a further drift-free sensor for releasing digital signals to a the data processing unit. The data processing unit releases the signals obtained by the sensor within a common temperature region of both sensors.
