[0002] In many fields such as industrial production, power systems, aerospace, etc., it is crucial to accurately monitor the micro-water density in the environment. Excessive micro-water content can have a serious impact on the performance, lifespan, and operational safety of equipment, such as causing electrical equipment insulation performance to decline, metal parts to corrode, and chemical reactions to be abnormal. Therefore, micro-water density online monitoring devices have emerged and are playing an important role in various industries. Existing micro-water density online monitoring devices have achieved certain results in realizing micro-water density monitoring functions, but there are still some problems to be solved in actual application. Among them, the protection problem at the connection between the gas inlet and the monitored equipment pipeline is particularly prominent;
