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.
