Abstract: A circuit arrangement (1) for monitoring the temperature of an electronic component (2), which, in particular, can be impinged with an electric current and can be connected to at least one voltage source (3). The circuit arrangement is able to guarantee safe monitoring of the temperature of an electronic component impinged with electric current by the electronic component (2) being part of at least one Wheatstone bridge (7) and by at least one switching device (8) being provided that influences the impingement of the electronic component (2) with electric current on the basis of a bridge transverse voltage of the Wheatstone bridge (7). Additionally, circuit arrangement (1) is well suited for use in a calorimetric mass flowmeter (18).

Abstract: A sensor arrangement including a probe and a bracket that are provided for a calorimetric mass flow meter for measuring the mass flow in a measuring tube. The probe is mounted in the bracket in such a manner that the probe is guided essentially without contact with a radial spacing through a probe recess a wall of the measuring tube and is positioned in a cross section of a flow-through area of the flow of the measuring tube. The bracket is designed in such a manner that the probe is thermally de-coupled from the measuring tube. The sensor arrangement for the calorimetric mass flow meter is capable of increasing the measuring accuracy and increasing the flexibility during operation.
