[0002] In industrial production, since some measured media have the characteristics of high temperature and high pressure, when analyzing data of such high-temperature and high-pressure media: usually, artificial sampling is used for detection. Due to the high-temperature and high-pressure characteristics of the monitored media, when analyzing by artificial sampling, the representativeness of the analysis data may be small due to the small sample size, which may affect the final judgment, and the change trend cannot be viewed in real time continuously. In addition, the temperature has a great influence on the measurement of conductivity. Only by performing low-temperature treatment on high temperature and high pressure can more accurate detection results be obtained. Especially when judging whether there is a leakage or an expanding trend of leakage points in high-temperature and high-pressure equipment in industrial production, a device is urgently needed to realize real-time monitoring of the conductivity of high-temperature and high-pressure media.
