Abstract: A sensor apparatus for detecting at least one property of a fluid medium, in particular of an exhaust gas of an internal combustion engine, and to a method for furnishing a sensor apparatus of that kind. The sensor apparatus encompasses at least one protective housing for reception of at least one sensor element in an inner housing, the inner housing being surrounded at least partly by an outer housing. The outer housing is secured with reference to the inner housing by way of a press fit, in particular over a portion. The sensor apparatus according to the present invention exhibits good resistance to thermal shock simultaneously with good sensor element dynamics, and allows an oriented design of the protective housing to be furnished.

Abstract: A contact element for contacting a contact point formed on a body includes: an element section on the contact point side for a force-locking connection to the contact point, an element section on the connection side for connection to an electrical connection conductor, and an intermediate section which connects the two element sections to one another for compensating for thermal expansions. At least the element sections on the contact point side and on the connection side are made of different integrally bonded materials having material properties which are adapted to the functionality of the corresponding element section.
