发明名称 Protection of gas communication in a electrochemical sensor
摘要 An electrochemical sensor for detection of a gas in an atmosphere containing the gas. The sensor has a housing having an electrochemical gas sensor with an electrolyte and at least two electrodes, one electrode being a gas sensing electrode. The housing has an orifice between the sensing electrode and the atmosphere for transmission of gas from the atmosphere to the sensing electrode, the orifice being protected by a hydrophobic membrane, and connected to at least two radial channels extending from the orifice. Each of the radial channels is connected to a common channel, such that gas communication from the atmosphere through the orifice to the sensing electrode is through the common channel and the radial channels, in addition to the covering membrane if the membrane is gas permeable.
