  • Patent number: 10837929
    Abstract: An arrangement for preparation of a distillation measurement of a liquid includes a heater and a traversing system. The heater supports a perforated plate selected from a group of standardized perforated plates which further supports a container containing the liquid. The heater is enabled and controlled during the performance of a standardized test for determining evaporation properties of the liquid. The traversing system is adapted to traverse the heater and to interrupt a further traversing of the heater, if a pressure force of the perforated plate put onto the heater against the container reaches a threshold value.

  • Publication number: 20190353603
    Abstract: An arrangement for closing a container, in particular a flask, for determining evaporation properties of a liquid in the flask according to at least one standardized test. The arrangement has at least one temperature measurement system, a sensor, a closing element adapted for contacting a surface of an opening in the container for closing the container and having a through-opening through which a portion of the temperature measurement sensor is guided such that a lower end of the sensor is arranged within the container. The arrangement further includes a mechanism for adjusting a position of the lower end of the sensor along a longitudinal direction of the temperature measurement sensor.

  • Patent number: 9846060
    Abstract: An optical sensor arrangement for measuring an observable, the arrangement including an optical resonance circuit including at least a first and a second optical resonator, each of the optical resonators including an entry port for coupling light into the optical resonator and a drop port for decoupling light from the optical resonator. The first and second resonator are configured such that only a portion of the first and second resonator detects the presence of the observable, a size of the portion of the first resonator being different from a size of the portion of the second resonator. The optical resonance circuit further configured to be coupled to a light generation circuit and to a detector unit for detecting light.

  • Patent number: 9677996
    Abstract: An optical sensor arrangement for measuring an observable including at least one light source for generating a first light component of a first frequency including a first mode and a second light component of a second frequency including a second mode orthogonal to the first mode, an optical resonator having differing optical lengths for the first and second modes, at least one of the optical lengths being variable depending on the observable and a dependence of the respective optical length being different for the first and second modes, and a detector unit coupled to the optical resonator for coupling out the two light components and being configured for detecting a frequency difference between a resonance frequency of the optical resonator for the first mode and a resonance frequency of the optical resonator for the second mode.

  • Patent number: 9097648
    Abstract: The present disclosure relates to an example method and optical sensor for detecting molecules of a particular substance by means of an optical sensor. Such an example method may include bringing the sensor into contact with a fluid to be analyzed, coupling light of a first wavelength into an optical resonator of the optical sensor, coupling light of a second wavelength into the same resonator or into a second optical resonator of the optical sensor, detecting, for each of the first and the second wavelengths, an optical signal coupled out of an optical path containing the respective resonator, varying an optical length of the respective resonator or the respective wavelength and detecting a broadening of this resonance indicating an absorption of the light fed into the respective resonator by molecules accumulated at the active layer of this resonator.

  • Patent number: 9080953
    Abstract: A sensor arrangement including a light source, a first optical element, a second optical element, a first photo detector, and a second photo detector. The light source is optically coupled to the first optical element that is optically coupled to the second optical element. The first photo detector is optically coupled to the first optical element for detecting a first component of the part of the light which is not transmitted by the second optical element, and the second photo detector is optically coupled to the second optical element for detecting a second component of the part of the light which is transmitted by the second optical element. One of the first and the second optical elements is an optical filter and the other is a sensor element, where the sensor element or the filter is tunable.
