Sensor e.g. oxygen sensor, for use in exhaust system of motor vehicle engine for e.g. detecting component in atmosphere, has metallic cover layer i.e. plating layer, formed at outer surface of front-sided separating layer

摘要

The sensor has a protecting outer pipe element (12) covering an outer surface of an outer pipe element (11). The outer pipe element has a sealing layer (A) in contact with the protecting outer pipe element that is rotating directly or by another outer pipe element. A front-sided separating layer (R1) is arranged before the sealing layer at a distance from the protecting outer pipe element and turns toward the protecting outer pipe element. A metallic cover layer i.e. plating layer (M), is formed at an outer surface of the separating layer of the outer pipe element.
