Abstract
An electrochemical gas sensor. One embodiment of the sensor may include a sensor body having a cavity, an electrolyte solution in the cavity, an auxiliary electrode in contact with the electrolyte solution, a sensing electrode in contact with the electrolyte solution, and a first baffle mounted within the cavity. The baffle comprises a plate with at least one aperture and serves to form a partial barrier for delaying the mixing process when liquid is added to the electrolyte solution. The sensor may also include a second such baffle. Also a method for mixing a liquid with electrolyte solution of an electrochemical sensor. The method includes forming a first barrier within the cavity and controlling the flow of the liquid introduced through the first barrier. The method may include forming a second such barrier and controlling the flow of the liquid through the first and second barriers.
