Optical sensor combined with the OUA260 flow assembly for the measurement of color concentrations

Application

The sensor is used to measure color concentrations in the range of the visible electromagnetic spectrum.

  • Color scale measurement: APHA/Hazen, EBC, ASBC, ASTM, ICUMSA
  • Measurement of color concentration
    • Outgoing goods inspection/purity monitoring
    • Color assurance
    • Discoloration control
    • Distillation monitoring
Your benefits
  • As slightest color changes are detected, production quality is guaranteed
    • Measuring range up to 2.5 AU or 50 OD (depending on optical path length)
    • Can be configured to measure color concentration at discrete wavelengths in the visible regionregion
    • Outstanding filter properties for highest linearity
    • Direct concurrence with laboratory values
    • Integrated reference detector for the compensation of particles, bubbles and lamp aging
    • Incandescent lamp for long service life and stable measured values
  • Cost-effective, time-efficient verification (liquid-free)
  • FM- and ATEX-approved lamps for applications in the hazardous area
  • Deployable and durable in numerous applications: Variety of materials and process connections
  • 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

The measuring principle is based on the Lambert-Beer law.

There is a linear dependency between the absorption of light and the concentration of the absorbing substance:

A = -logA m = ε . c . OPL
A ... absorption, A m ... absorption measured by detector
ε ... Extinction coefficient
c ... Concentration
OPL ... Optical path length

A light source emits radiation through the medium and the incident radiation is measured on the detector side.

A beam splitter splits the light into two beams. One beam is used for measuring while the other acts as a reference to compensate for particles, bubbles and lamp aging.

Once the light has passed through a filter for wavelength selection, the intensity of the light is determined by a photodiode and converted to a photocurrent.

The subsequent conversion to absorbance units (AU, OD) is performed in the associated transmitter.
