  • Generator vlažnega zraka za umerjanje higrometrov = Humidity generator for calibration of hygrometers
    Pohl, Marjan ; Bajsič, Ivan
    This paper presents a facility for humid air generation - humidity generator. The generator was developed for calibration of hygrometers. The principle of operation is based on the two-temperature ... method for humid air generation and the open circuit flow mode is applied. Saturation of the air is achieved by the water droplets atomization in air flow. The generator is designed to operate in the test chamber range from 5 to 80°C and in dew point range from 5 to 35°C. For calibration purpose the comparison method is applied using the suitable reference humidity sensor. The quantity of the water dispersed in air flow and in this way the air humidity in the test chamber can be also influenced by changing the pressure of the water disperse pouts system. Fast change of the pressure is followed by the change of the humidity in a very short time. Maintenance the stable temperature at the same time enables stationary air humidity conditions in the test chamber. Operation of the system is supervised by the software developed in LabView environment.
