Abstract: An optoelectronic apparatus for transmission of an electrical signal via, galvanically isolated by means of a one-piece, translucent, plastic body, an input current circuit. At least one optical transmission element, and an output current circuit, having at least one optical receiving element, wherein the optical transmission element has a principle transmission axis and the optical receiving element a principle receiving axis, which are oriented so as to concide with a shared optical axis.

Abstract: An apparatus for determining and/or monitoring at least one process variable. The apparatus includes at least one, first electronics unit, at least one, second electronics unit, and at least one transferring unit. The transferring unit is arranged between the first electronics unit and the second electronics unit, and the transferring unit is embodied in such a manner, that it transmits electrical energy and data between the first electronics unit and the second electronics unit.

Abstract: An apparatus for capacitive determining and/or monitoring of fill level of a medium in a container. The apparatus includes: A probe unit; a control unit, which supplies the probe unit with a drive signal; and an evaluating unit, which receives a response signal from the probe unit and which determines from the response signal a statement concerning fill level. Stored in the evaluating unit are at least a first and a second formula or a first and a second evaluating algorithm; and, in case accretion lies below a predetermined limit value, the evaluating unit determines the statement concerning fill level via a first formula and, in case accretion lies above the predetermined limit value, the evaluating unit determines the statement concerning fill level via a second formula.

Abstract: A housing comprises a first housing part, having a first bearing surface for a first contact surface of a sealing ring, and a second housing part, which can be screwed together with the first housing part and has a second bearing surface for a second contact surface of the sealing ring. The first contact surface of the sealing ring is produced from a first material having a first coefficient of friction in relation to the material of the first bearing surface, the second contact surface of the sealing ring is produced from a second material that has a second coefficient of fiction in relation to the material of the second bearing surface, and the first coefficient of friction is smaller than the second coefficient of friction.
