| titleOfInvention | Ultra-low dew point measurement method using quartz microbalance dew point sensor |
| abstract | The present invention relates to a crystal microbalance dew point sensor for measuring ultra low dew point through cooling with liquid nitrogen, and a method for measuring ultra low dew point using the same, and more particularly, while lowering the temperature of a crystal oscillator very low using liquid nitrogen, The present invention relates to a crystal microbalance dew point sensor for determining a dew point by measuring a resonance frequency change and temperature of a crystal oscillator according to temperature change, and a method for measuring a low dew point using the same. To this end, the present invention is a crystal oscillator; A crystal oscillator holder in contact with an edge of the crystal oscillator and having a platinum resistance temperature element attached to one surface thereof; A heat absorption device for controlling the temperature of the crystal oscillator holder and the crystal oscillator using liquid nitrogen; And a liquid nitrogen supply device for automatically supplying liquid nitrogen to the heat absorption device, wherein the dew point is determined by measuring a resonance frequency change and a temperature of the platinum resistance temperature element according to a temperature change of the crystal oscillator. It provides a modified microbalance dew point sensor. |
