[0002] The resistance-capacitance method for detecting moisture content in flue gas is a device that measures the water vapor content in flue gas based on changes in resistance and capacitance. It is widely used in industrial flue gas, boiler exhaust gas, and air humidity detection, and is particularly suitable for measuring moisture content in high-temperature and high-humidity environments.

[0003] The resistance-capacitance method flue gas moisture content detection device uses a humidity sensor for detection. However, the flue gas being detected contains a large amount of dust and other impurities. When the humidity sensor is in operation, these dust and other impurities are easily adsorbed onto the sensor. If too much adsorption occurs, it will affect the sensor's detection accuracy, thereby affecting the accuracy of the data.

[0004] Therefore, it is necessary to design a resistance-capacitance method for detecting the moisture content of flue gas to solve the above problems. Utility Model Content
