Embodiment Construction

[0071] figure 1 A first example of an embodiment of an absorption measurement system of the invention for measuring at least one property of a medium reflected in its absorption behavior is shown.

[0072] In this case the absorption coefficient μ is measured as a dominant property of the medium; the frequency associated with a predetermined frequency range or as a variable averaged over a predetermined spectral range for which the absorption is determined according to an embodiment of the absorption measurement system Coefficient μ.

[0073] Based on these absorption coefficients μ, corresponding evaluation methods can be used to determine other properties of the medium reflected in the absorption behavior of the medium, such as, for example, certain substances contained in the medium and / or the concentration of such substances, and such as, for example Turbidity or coloring properties. Furthermore, other properties such as, for example, the total organic carbon content or ...

Abstract

The present invention describes an absorption measurement system that can be used flexibly over a large measuring range to measure at least one property of a medium reflected in its absorption behavior, in particular properties such as the absorption coefficient (μ) of the medium . The absorption measuring system comprises: a measuring chamber (1) filled with a medium in measuring operation, wherein a radiative optical path which can be used as a measuring path (M) and has a different length (L) extends completely through the medium; A transmitting unit (3) that emits radiation along a measurement path (M) through the measurement chamber (1) during measurement operation; receives radiation that passes through the measurement chamber (1) on the measurement path (M) and measures its dependence on a measuring and receiving unit (5) for the radiation intensity (I) of the medium property and the measurement path length (L); and for determining said property based on the measurement radiation intensity (I) and the length (L) of the measurement path (M) Measuring electronics (7).

Description

technical field [0001] The invention relates to an absorption measurement system for measuring at least one property of a medium reflected in its absorption behavior, in particular a property such as at least one absorption coefficient, the absorption measurement system comprising, in the measurement operation, filled with a medium a measuring chamber; a transmitting unit that emits radiation through the measuring chamber during a measuring operation; and a measuring and receiving unit that receives the radiation passing through the measuring chamber and measures the intensity of the radiation depending on the absorption in the medium; and based on the measurement Measuring electronics that determine the properties of a medium by radiating intensity. Background technique [0002] Absorption measurement systems are used today in a large number of industrial applications, especially in the chemical and biochemical industries, and in water or wastewater treatment, to measure ab...
