Apparatus for holding a measuring electrode

摘要

Apparatus for holding a measuring electrode (10) comprises a housing (4) and an inner sleeve (8) axially gliding in the housing (4). The inner sleeve (8) is made of ceramic material or has a media-side section of ceramic material or has a ceramic coating. The inner sleeve (8) of media-side section of the housing feeds into a housing bearing section of ceramic material or in a ceramic bushing (26,28) or plastic bushing (52,54). The material of the plastic bushing is softer than the ceramic material of the inner sleeve so that particle dirt is pressed into the material of the plastic bushing.
