Publication number: 20220252509Abstract: A measuring device for determining a substance concentration of a fluid arranged in a measurement volume includes a source emitting a source spectrum, a wavelength-selective means arranged before the measurement volume, a measurement space limiting the measurement volume at least in a beam path, and a detector for measuring a wavelength-related absorption of a measurement spectrum having passes through the measurement volume. A fluorescence-reducing element is arranged in the beam path between the detector and the measurement volume. A beam splitter is arranged between the source and the measurement volume.Type: ApplicationFiled: June 29, 2020Publication date: August 11, 2022Applicant: Optek-Danulat GmbHInventors: Daniel Platte, Peter Schroeren

Publication number: 20190226982Abstract: A flow-through measuring cell having one inlet opening for entry of the fluid, and one outlet opening for exit of the fluid. A single measurement space is located between the inlet opening and outlet opening. A radiation measurement region is provided for measuring the interaction of the fluid in the measuring cell with electromagnetic radiation from outside the measuring cell. The radiation measurement region is bordered by two opposite windows of which one is intended for inlet and the other for exit of the electromagnetic radiation. The measuring cell has a positioning range with several operating positions with a different distance A, A? between the windows into which the measuring cell can be set without rotation.Type: ApplicationFiled: April 4, 2019Publication date: July 25, 2019Applicant: OPTEK-DANULAT GMBHInventors: Daniel Platte, Peter Schroeren, Jurgen Danulat, Andreas Reese

Patent number: 9354193Abstract: Device for measuring electrical conductivity of a liquid medium comprising constant voltage means, connected to a first electrode arrangement for injecting an alternating signal into the liquid medium, detection means, connected to a second electrode arrangement coupled via the liquid medium, for generating a measurement signal influenced by the electrical conductivity with a clock frequency (CLK) of the alternating signal, and evaluation means which from a current-proportional injection signal of the current injected by the first electrode arrangement into the liquid medium and from the measurement signal generate a conductivity signal of the liquid medium. The constant voltage means are made in an individual circuit branch which has commutator means for the first electrode arrangement and ohmic resistance means in a series connection, the current-proportional injection signal being tapped as a voltage drop over the resistance means.Type: GrantFiled: June 26, 2012Date of Patent: May 31, 2016Assignee: Optek-Danulat GmbHInventors: Daniel Platte, Alfred Pohl
