    摘要： The invention relates to a device (1) for determining and/or monitoring the temperature (T) of a medium, comprising at least one temperature sensor (2) and at least two reference elements (3, 3a, 3b) for the in situ calibration and/or validation of the temperature sensor (2). The first reference element (3a) consists at least partly of a first material, for which at least one phase transition of at least the second order occurs at at least one first specified phase transition temperature (T
    ph,1 ) in the temperature range that is relevant to the calibration of the temperature sensor (2), and the second reference element (3b) consists at least partly of a second material, for which at least one phase transition of at least the second order occurs at at least one second specified phase transition temperature (T
    ph,2 ) in the range that is relevant to the calibration of the temperature sensor. The at least two reference elements (3a, 3b) are contacted by precisely two connection wires (4c, 4d).

    摘要： The invention relates to a device (1) for determining and/or monitoring the temperature of a medium, comprising at least one temperature sensor (2) which has at least one sensor element (3) and an electronic unit (4), wherein the electronic unit (4) has at least one input unit (5) at least for inputting at least one comparison temperature (T
    c ) of a comparison medium and/or at least of one tolerance range (ΔT
    tol ) for the at least one comparison temperature (T
    c ), and comprises a display unit (7), wherein the electronic unit (4) is designed to determine and/or monitor the temperature (T
    m ) of the medium, and wherein the electronic unit (4) is designed to detect whether the temperature sensor (2) is immersed at least partially in at least one comparison medium which has a known comparison temperature (T
    c ), and in the event that the temperature sensor (2) is immersed in a comparison medium, to perform a comparison measurement in order to calibrate and/or validate the sensor element (3), with which measurement the temperature of the comparison medium is determined in the form of a comparison temperature measured value (T
    cm ) on the basis of a receiving signal received from the sensor element (3), and to display the performing of the comparison measurement and/or the comparison temperature measured value (T
    cm ) by means of the display unit (7).

    摘要： The invention relates to a method for operating a measuring device (1), comprising the steps: determination of a flow rate; comparison of the determined flow rate to a threshold value corresponding to a critical stress, in particular a resonant frequency of an immersion element (3) of the measuring device (1), said element projecting into the flow; and output of a message signalling that a critical flow and/or frequency has been reached.
