Turbidity sensor, in particular for determining a cell density of a suspension

Abstract

A turbidity sensor for detecting clouding of a fluid by particulates contained in the fluid, wherein the turbidity sensor includes a fluid detection region for the reception and metrological detection of fluid; a radiation source for emitting radiation into the fluid detection region; a first radiation sensor for detecting a first part of the radiation emitted by the radiation source; and a second radiation sensor, different from the first radiation sensor, for detecting a second part of the radiation emitted by the radiation source that is different from the first part, wherein at least a portion of the fluid detection region is located between the first radiation sensor and the second radiation sensor, the second radiation sensor is located in a beam path of the first part of the radiation emitted by the radiation source that is detected by the first radiation sensor.
