Measurement device for quantitatively detecting constituents of a pulp/fluid mixture for paper and/or cardboard production. The device includes at least one radiation source for irradiating the mixture in a number of definite, different wavelength ranges. The device also includes at least one sensor for measuring the intensity of radiation that has been influenced by the mixture, and at least one set of measurement electronics. Each sensor detects only one of the definite, different wavelength ranges of the radiation at a particular time.

Measurement device for quantitatively detecting constituents of a pulp/fluid mixture

Process and measurement device for quantitatively detecting constituents of a pulp/fluid mixture for paper and/or cardboard production. The device includes at least one radiation source for irradiating the mixture in a number of definite, different wavelength ranges. The device also includes at least one sensor for measuring the intensity of radiation that has been influenced by the mixture, and at least one set of measurement electronics. Each sensor detects only one of the definite, different wavelength ranges of the radiation at a particular time. The process includes irradiating the mixture with at least one radiation source, the irradiation occurring in a number of definite, different wavelength ranges; and measuring the intensity of radiation that has been influenced by the mixture by at least one sensor. Each sensor detects only one of the definite, different wavelength ranges of the radiation at a particular time. The measurement device is adaptable for use in sections of a pulp density regulated headbox of a paper making machine, in inflows and/or outflows of a vat belonging to a paper machine or part thereof, in a region of a wet section of a paper machine, and in white water of a paper machine.
