Abstract: The present disclosure relates to a method for producing an exchangeable electrode assembly, with at least one sensor body and at least a first electrode, for an electrochemical sensor for determining the concentration of an analyte in a gaseous or liquid measurement medium, a corresponding electrode assembly, and an electrochemical sensor with an electrode assembly according to the present disclosure. In order to produce the electrode assembly, the following method steps are performed: providing a sensor body, and applying at least a first electrically-conductive material to a first sub-region of the sensor body for producing a first electrode of the electrode assembly.

Abstract: A centrifugal type oil cleaner having a housing with rotor therein and passageways for feeding the oil into the bottom of the rotor and past narrow spaces for separating the oil and contaminations with the clean oil going out openings in the rotor rotating said rotor and them passing to a bottom outlet in said housing for reuse.
