Optical sensor for the measurement of VIS/NIR absorption

Application

The OUSAF11 sensor measures the VIS/NIR absorption of liquids.

  • Interphase detection
  • Applications in the food and beverage industry
    • Milk detection in CIP solutions
    • Phase separation, e.g. milk/water
    • Product loss detection in outlet
  • Measurement of solids in:
    • Primaries industry
    • Mining
Your benefits
  • Cost savings and less product loss thanks to fast interphase detection:
    • Measuring range 0 to 3 AU (absorbance units)
    • Two path lengths available: 5 and 10 mm
    • Low-voltage incandescent lamp
  • High degree of product safety owing to non-glass, robust and hygienic design:
    • Stainless steel housing and sensor head made from dirt-repellent FEP
    • FDA-compliant materials and 3-A certification
    • CIP/SIP-resistant
  • Easy maintenance saves time and costs
  • Flexible
    • Submersible sensor for applications in open tanks and basins
    • Insertion sensor with Triclamp or Varivent connection for hygienic applications in pipes and vessels
    • Color-independent measurement with optional NIR detector
    • Operating temperature range 0 to 90 C (32 to 190 F)
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.

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.
