AISI 316 SS Through flow cell c/w chemical cleaning system Mod.701C4A0A0

Through flow cell for the measure of turbidity, nephelometric type.
Measuring system includes a light source and a light receiver. The emitted light beam hits the liquid surface and is scattered by the suspended particles in the sample. The scattered light is measured at 90° (light scattering 90°); the intensity of this scattering is proportional to suspended solid content in the sample. This system is based on a single light beam and is called 'nephelometric'.
Measuring range: 0-2 / 2000 NTU.   Measuring units are NTU (Nephelometric Turbidity Units).
Power supply to the cell is highly stabilized in order to assure a constant intensity of the emitted light; light source assures a long term stability (many years) for the emitted light (594 nm). Light receiver is large surface, CdS type, encapsulated into a stainless steel housing sealed under vacuum conditions and responds to 550 - 600 nm light.
The optical group is immersed into the process liquid but only the light receiver is in contact with the sample.
Turbidity measure is expressed in NTU engineering units (Nephelometric Turbidity Units). The cell is completely made of Stainless steel, AISI 316  and is supplied c/w brackets for wall mounting. Process connections are two sanitary type connections, DN15.
Sample flowrate into the cell: lower than 0,5 lt/min
The cell includes the sensor chemical cleaning system. The cleaning sequence ca be directly driven by Mod.uP transmitter.
