  • Patent number: 10591499
    Abstract: The disclosure concerns a method for operating an automated analyzer, including transporting a liquid containing a plurality of particles into a chamber, such as a reactor chamber and/or measuring cell chamber of the analyzer, introducing a gas or gas mixture, for example, air into the chamber, such as through the liquid present in the chamber so that the particles in the liquid are stirred up, and subsequently draining at least part of the liquid from the chamber through a fluid line ending in the chamber and an open valve arranged in the fluid line.
    Type: Grant
    Filed: March 30, 2017
    Date of Patent: March 17, 2020
    Assignee: Endress+Hauser Conducta GmbH+Co. KG
    Inventors: Michael Littmann, Ulrich Rottensteiner

  • Patent number: 9651479
    Abstract: A method and analyzer for determining a measured value of a measured variable of process automation technology in a liquid or gaseous medium by means of an optical sensor includes taking a sample of the medium; mixing the sample with one or more reagents; supplying an emitter of the optical sensor with an exciter signal for producing sent light, wherein the sent light by interaction with the mixed sample is converted into received light as a function of the measured variable; producing a receiver signal by means of a receiver of the optical sensor from the converted, received light; and determining the measured value based on the receiver signal and a calibration function, which includes a term which takes aging of the reagents into consideration.

  • Patent number: 9632019
    Abstract: An apparatus and method for cleaning deposits and accretions from an end plate of a sensor body, for accommodating a measuring apparatus for determining one or more physical and/or chemical, process variables. The sensor body is sealed against penetration by liquid and a wiper is provided having a wiper blade for cleaning the end plate. The wiper is arranged as a subcomponent on a peripheral, appended module, wherein geometries of the wiper and the peripheral, appended module are so embodied that the wiper in the case of rotary movement from a rest position into a cleaning position, with the lower edge of the wiper blade being flush with the upper edge of the end plate, in the cleaning position, and in order that the wiper cleans the end plate by contact of the wiper blade with the end plate, and the wiper then returns to the rest position.

  • Publication number: 20150285736
    Abstract: A method and analyzer for determining a measured value of a measured variable of process automation technology in a liquid or gaseous medium by means of an optical sensor, which has at least one emitter for sending light of at least two wavelengths, and a receiver associated with the emitter for receiving of received light, comprising the steps as follows: taking a sample of the medium; mixing the sample with one or more reagents; supplying the emitter with an exciter signal for producing the sent light, wherein the sent light by interaction with, especially by absorption by, the mixed sample is converted into received light as a function of the measured variable; producing a receiver signal by means of the receiver from the converted, received light; and determining the measured value based on the receiver signal and a calibration function.
