Gas probe with hygroscopically coated protective device, method of producing a gas probe and exhaust gas purification component and vehicle having a gas probe

摘要

A gas probe, in particular a lambda probe for the analysis of exhaust gases from a mobile internal combustion engine, includes at least one protective device, at least partly surrounding a sensitive sensor element of the gas probe, which comes into contact with a gas. The at least one protective device includes a gas contact face which at least partly has a hygroscopic surface.
