Optical sensor with the OUA260 flow assembly for the measurement of turbidity and undissolved solids

Application

The scattered light turbidity sensor is used to measure undissolved solids, emulsions and immiscible media in process liquids.

  • Outgoing goods inspection/purity monitoring
  • Filter control
  • Condensate regulation
  • Turbidity measurement in
    • Breweries
    • Drinking water
    • Brine
  • Leak detection in heat exchanger
Your benefits
  • Quality control of products and processes with the precise measurement of minute particle concentrations up to the equivalent of 0 to 200 FTU Formazin or 0 to 200 ppm diatomaceous earth through the use of scattered light detection at an angle of 11 from the excitation beam
  • Operational safety thanks to low-voltage incandescent lamp for long service life and stable measured values
  • Optional broadband NIR filter minimizes color-related measured errors
  • FM- and ATEX-approved lamps for applications in the hazardous area
  • Deployable and durable in numerous applications:
    • Variety of materials and process connections
    • Pyrex window for precise, reproducible performance under industrial conditions, quartz or sapphire window optionally available
  • Hygienic design for high degree of product safety: certified materials and CIP/SIP resistance
  • Can be adapted to process requirements: Optional air purge ports to prevent the formation of condensate on the optical windows
Measuring principle Turbidity

Turbidity refers to the appearance of a liquid that contains suspended particles. The presence of these particles causes the light to be scattered and absorbed, giving the liquid a turbid, or cloudy, appearance. The amount of light scattered or absorbed in a liquid can be used in a measuring system to determine the degree of turbidity.

Scattered light method

A focused parallel beam of light is passed through the medium. This beam is known as the transmitted light and is measured by a transmitted light detector. If the medium does not contain any particles, the transmitted light detector detects all the light transmitted by the light source. If there are particles in the medium, the light is scattered in all directions, but primarily in a forward direction. The optical system is designed such that the scattered light is measured at an angle of 11. This angle of measurement ensures that the maximum scattering signal present is detected at the scattered light detector.

Measuring system

An optical measuring system comprises:

  • Sensor (photometer) OUSTF10
  • Liquiline CM44P transmitter
  • Cable set CUK80
  • Assembly to suit the sensor, e.g. OUA260
