  • Patent number: 10309837
    Abstract: A measuring device, in particular for use in the process measurement technology, including a cylindrical sensor tip which includes a closed housing, a sensor element disposed within the housing in the form of a temperature dependent resistor and for generating a sensor signal, and electronic components, which are connected to the sensor element via electrical connecting lines and/or a conductor film, wherein said sensor element is thermally connected to the housing by means of a solder and a heat conducting, electrically insulating layer is disposed between the sensor element and the solder is provided.
    Type: Grant

  • Patent number: 9243941
    Abstract: A magnetic-inductive flowmeter with a nonconductive measuring tube, a magnetic field generating apparatus, two measuring electrodes conductively coupled to the medium for tapping a measuring-circuit voltage induced in the flowing medium, and with a measuring device for detecting an empty tube. Detection of an empty tube is obtained by the measuring device being an admittance measuring device having a detector, a counter-electrode, an ac signal source and an evaluation unit, the detector having an electrode connected to the ac signal source so that the electrode is exposed to an ac signal in the range of roughly 50 MHz-200 MHz and then an electrical field extends from the electrode into the medium. The electrode of the detector and the counter-electrode planiform shaped and are located essentially opposite one another on the outer surface of the measuring tube above and underneath the longitudinal axis of the measuring tube, respectively.
