Abstract
A sensor element is proposed, particularly a lambda probe for analyzing exhaust gases in internal combustion engines, having a protective device which, at least region-wise, surrounds or covers a sensitive component of the sensor element exposed to a gas. Also provided is that the protective device has an arrangement or is joined to such an arrangement by which the admission of gas to the sensitive component is able to be regulated.
