Abstract
An electrochemical oxygen sensor is provided. The electrochemical sensor includes a housing having first and second compartments, a sensing electrode disposed within the first compartment of the housing, a consumable anode disposed within the second compartment of the housing, a porous separator between the sensing electrode and consumable electrode that separates the first and second compartments and an electrolyte saturating the porous separator and consumable anode. A first aperture on a first end of the housing extends between an outside surface of the housing and first compartment that allows gas access to the sensing electrode. A venting system on a second, opposing end of the housing includes a second aperture extending between the outside surface of the housing and second compartment and has a predetermined permeability that controls pressure in the second compartment and loss of moisture from the sensor.
