Abstract

The invention relates to a super-low range turbidity sensor. According to the invention, a heating element is added on a light source part, a lens of the light source part is kept at constant temperature, Atomized condition of the light source part can be overcome, and detection accuracy of the turbidity sensor is increased. The turbidity sensor comprises an upper housing, a lower housing, a detection control integrated circuit, a light source and a photoelectric converter member; the photoelectric converter member comprises several photoelectric conversion monomers, the photoelectric conversion monomers are connected in series to form a ring; the light source and light-transmission through holes are arranged in the upper housing, a water channel pipe as a water body turbidity detection area is arranged in the lower housing; a transversely penetrated recess cavity is arranged between the upper housing and lower housing, and an open-type isolation region is arranged between the upper housing and the lower housing by the recess cavity.

Description

technical field [0001] The invention belongs to the field of optical properties of water bodies, in particular to an ultra-low range turbidity sensor. Background technique [0002] Turbidity is a characteristic parameter of the optical properties of water. It is not only one of the important indicators to measure the goodness of water quality, but also an important basis for evaluating the effect of water treatment. Therefore, the online detection of water turbidity has very important practical significance. The methods of turbidity analysis can be divided into: transmission method and scattering method. Compared with the transmission method, the scattering method has the advantages of high sensitivity and low detection limit when measuring low turbidity. [0003] At present, the turbidity detection of water body is mainly carried out by scattering method. A turbidity sensor using a scattering method for turbidity detection. Due to structural design, the detection performan...
