摘要： A Coriolis mass flow meter comprises a vibration element, an exciter assembly, a sensor assembly, and an electronic transformer circuit electrically coupled to the exciter assembly and the sensor assembly. The vibration element is contacted by the flowing fluid. The exciter assembly is designed to convert electric power into mechanical power to produce mechanical vibrations of the vibration element. The transformer circuit generates an electric driver signal and feeds electric power to the exciter assembly. The vibration element mechanically vibrates with a vibration frequency specified by the electric driver signal. The sensor assembly has two electrodynamic vibration sensors designed to convert vibrational movements of the vibration element at a first or at a second measurement point into electric vibration measurement signals having an AC voltage component with a frequency and with an amplitude based on the frequency and on a magnetic flux flowing through the respective vibration sensor.

摘要： An intrinsically safe circuit arrangement for supply of electrical power to a consumer having a maximum power requirement, comprising: a voltage source; a voltage monitor for limiting an output voltage to a maximum value; an electrical current limiting resistor for limiting an output electrical current to a maximum value; and an actively controlled electrical current limiting circuit for limiting output electrical current to an electrical current limit value, wherein the electrical current limiting circuit is embodied such that it controls at least the output current to the electrical current limit value as a function of a voltage drop across a part of the electrical current limiting circuit, when a loading of the circuit arrangement above the nominal load is present, such that an adapting of the electrical current limit value occurs, preferably based on a predetermined characteristic curve.

摘要： A measuring arrangement of the invention includes: At least one measuring device, which generates, repeatedly during operation, measured values, especially digital, measured values, representing the at least one measured variable to be registered; as well as an electronic data processing system superordinated to the at least one measuring device, especially a data processing system which is spatially distributed and/or spatially remote from the measuring device. Measuring device and data processing system are connected together by means of at least two line-pairs, through each of which an electrical current flows, at least at times, during operation. According to the invention, the measuring device transmits the internally generated, measured values to the data processing system via both line-pairs. In this way, it is then possible to transmit a plurality of measured values simultaneously, when each of the two line-pairs is embodied as part of a two-conductor current-loop.
