Abstract: Sensor for household appliances, in particular washing machines and dishwashers, comprising a housing 2 which comprises first and second housing fingers 8, 10 extending from a basis, a first optical element 12 being arranged in the first housing finger 8, a second optical element 14 which is arranged in the second housing finger 10 wherein a sensing beam 16 transmitted and received by the optical elements 12, 14 is propagating between the housing fingers 8, 10 external to the housing 2 for sensing of the turbidity of a cleaning medium at least partially surrounding the housing 2, and a temperature sensor 18 which is arranged in the second housing finger 10 in a greater distance from the basis 4 compared to the second optical element 14 for sensing the temperature of the cleaning medium.

Abstract: The invention relates to a transmission sensor (1) for measuring the turbidity of a fluid, comprising a first and a second measuring section (2, 3). A transmitter (6) emits electromagnetic radiation into the two measuring sections (2, 3). A first receiver (14) is allocated to the first measuring section (2) and a second receiver (15) is allocated to the second measuring section (3). The transmitter (6) is inserted into a transmitter carrier (8) in such a way that the transmitter (6) is forced to adopt a predetermined oriented position. The receivers (14, 15) are inserted into a receiver carrier (18) in such a way that each of said receivers (14, 15) is forced to adopt a predetermined oriented position. A transmitter carrier holder (9) forcibly positions the transmitter carrier (8) in a predetermined location and a receiver carrier holder (19) forcibly positions the receiver carrier (18) in a predetermined location.

Abstract: For adjusting output voltages of a turbidity sensor which is used for measuring the turbidity of a medium by means of a radiation at least partially propagating through the medium being emitted from a sender and being received by a receiver, ohmic loads for the receiver on its output side are adjusted such that desired output voltages are obtained.
