Description

technical field [0001] The present invention relates to the technical field of dew condensation measurement, in particular to an imaging dew point meter. Background technique [0002] The working principle of the existing dew point meter is: when the gas to be measured enters the condensation chamber and passes over the mirror at a certain flow rate, the temperature of the mirror is higher than the dew point temperature of the gas, and the dry mirror almost totally reflects the incident light of the light source. When the dew point meter is used for measurement, the refrigeration device is first controlled according to the intensity of the reflected light detected by the photoelectric detector, so that the temperature of the mirror surface drops until the mirror surface condenses or frosts. The intensity of the light will change accordingly, and the photodetector senses the change of the reflected light signal and locks the temperature. The temperature at this time is the de...
