摘要： an improved oxygen concentration detector is described having an oxygen concentration sensor which produces an electromotive force in accordance with a difference between an oxygen concentration in the gas components of a gas under test and an oxygen concentration in a reference gas, and first and second electrodes formed on the gas-under-test side and the reference gas side, respectively, of the oxygen concentration sensor, so that the electromotive force produced by the oxygen concentration sensor is taken across the two electrodes, in which the improvement comprises a first protective member arranged to cover the first electrode on the oxygen concentration sensor and having a number of pores through which the gas under test can pass, and a second protective member arranged between the first electrode and the first protective member also having a number of pores through which the gas under test can pass. The first and second protective members are spaced apart from each other to form a gap between them and the pores of the first protective member and the pores of the second protective member are arranged in a staggered relationship to each other.The pores of the first protective member may have a louvered shape or the pores of the two protective members may partially overlap each other. The pore sizes for both of the protective members are preferably in the range of 0.5 mm to 3.0 mm.The detector assembly is effective in reducing the flow rate of the gas under test within the exposed detector so that the underlying electrode is not substantially peeled off.

摘要： an oxygen concentration detector of a waterproof construction comprises an oxygen ion conduction metal oxide (1) which produces an electromotive force in accordance with a difference between an oxygen concentration in gas component in a gas under test such as exhaust gas from an internal combustion engine of an automobile and an oxygen concentration in the atmosphere. The structure includes a coaxially arranged inner tube and an outer tube with the inner tube being housed in the outer tube with a water proof structure being interposed therebetween. The inner tube constitutes a lead wire to be electrically connected to that one of two electrodes for taking out the electromotive force which is created. The outer tube (18) serves to expose the inner electrode (2) to the atmosphere at a site such that water may not be splashed into the interior of the sensor.
