<p>The potentiometric sensor element comprises a measuring element and a shield housing permanently bonded to the measuring element, in which housing an electronic sensor unit is accommodated and which is sealed off against external influences. The electronic sensor unit is connected to a contactless interface adapted to exchange energy and signals with a corresponding contactless interface in an electronic base unit. The shield housing comprises an outer sleeve and an inner sleeve, accommodated within the outer sleeve, wherein the electronic sensor unit is accommodated in the inner sleeve and is surrounded there by a first casting compound. The filled inner sleeve is in turn bonded permanently to the outer sleeve by means of a second casting compound, which is different from the first casting compound.</p> |
