Description

technical field [0001] The invention relates to the field of sensors, in particular to the field of sensors for measuring the water content of gas. Background technique [0002] With the development of social economy, in the production process of various large-scale industrial enterprises (such as: coal mines, petroleum, air separation, etc.), in some production links, it is necessary to monitor the gases (such as: NO , O2, etc.) for the necessary water content (dew point) detection, in order to maintain normal production needs. Most of the existing technologies use thin-film capacitive sensors to measure micro-moisture content. Its detection principle is that the planar capacitance gold / alumina reacts humidity based on the change of capacitance value when measuring the humidity of the sample gas. The sensor is based on a layer of pure aluminum deposited on a ceramic substrate. The pure aluminum acts as the anode. A permeable gold film is deposited on the oxide layer. Alumi...
