    • The invention relates to a coil arrangement comprising an electric coil (10) and an armature (20) that can be moved between a first end position (I) and a second end position (II), an electronic switch (30) that can be switched between at least two switching states, a control and monitoring circuit (40) for generating a switching signal (ctrl) actuating the electronic switch (30), and an operating circuit (50) for providing an operating voltage (UN), and a current measuring signal (IM) representing a time curve of an electric current flowing in a coil circuit formed by means of the coil. The control and monitoring circuit (40) is further configured to carry out an inspection of the coil (10) using the current measuring signal (IM), namely, to determine whether an inductance L of the coil (10) shows a dependence on a time curve of the switching signal (ctrl), or a time curve that is corresponding to the time curve of the switching signal, for example. The electro-mechanical switch (100), in turn, comprises a first switching contact (101) that can be moved between a first switching position (i) and a second switching position (ii), a second switching contact (102), and a coil arrangement according to the invention for actuating the switching contact (101), whereas apart from such an electro-mechanical switch (100), the measurement transducer (Tr) also comprises a measurement circuit for receiving at least one pickup signal (s1) that is dependent upon a physical or chemical measurement variable, and/or represents a time curve of said measurement variable (x).

    • The measuring device electronic system comprises a processor and two clock generators (TG1, TG2). The clock generator (TG1) is used to generate a clock cycle signal (clk0) with a nominally constant clock frequency, f
      clk0_SOLL , said clock cycle signal clocking the processor, and to generate a reference clock signal (clk1) which is dependent on the clock cycle signal (clk0) and which has a nominally constant clock frequency, f
      clk1_SOLL , that is smaller than the clock frequency, f
      clk0_SOLL , of the clock cycle signal by a specified multiple. The clock generator (TG1) is used to generate a second reference clock signal (clk2) which is independent of the clock cycle signal (clk0) and which has a nominally constant clock frequency, f
      clk2_SOLL , that is smaller than the clock frequency, f
      clk0_SOLL , of the clock cycle signal by a specified multiple. Using the two independent reference clock signals (clk1, clk2), a frequency difference, Δf, can be ascertained, if present, during the operation of the measuring device electronic system or the measuring device produced with said electronic system, wherein the frequency difference represents a difference between the current clock frequency of the first reference clock signal and the current clock frequency of the second reference clock signal and thus represents a measurement of a deviation of a current clock frequency, f
      clk0_IST , from the nominally specified clock frequency, f
      clk0_SOLL , of the clock cycle signal.
