Transport and storage guard i.e. protective cap, for planar broadband lambda probe, has sealing bed that is formed such that protective tube linearly contacts sealing bed in pushed state in circumferential direction around cylinder axis

摘要

The guard (10) has a sensor housing in which a sensor for determination of a property of a measurement gas i.e. exhaust gas, in a gas measuring chamber is arranged. The sensor housing is provided with a threaded section. A sealing bed (24) or lip has an inner diameter that is smaller than an outer diameter of a protective tube during sliding of the guard on the protective tube. The sealing bed is formed such that the protective tube linearly contacts the sealing bed in a pushed state in a circumferential direction around a cylinder axis (16).
