Abstract: transducer apparatus comprises a transducer housing, a tube, a temperature sensor as well as a temperature sensor. The tube is arranged within a cavity of the transducer housing, in such a manner that an intermediate space is formed between a wall of the transducer housing facing the cavity inner surface and an outer surface of a wall of the tube facing the cavity. Furthermore, the tube is adapted to guide a fluid in its lumen, in such a manner that an inner surface of the wall of the tube facing the lumen is contacted by fluid guided in the lumen. Each of the temperature sensors is formed by means of a temperature detector arranged within the intermediate space as well as by means of a coupling body coupling the respective temperature detector thermally conductively with the wall of the tube and is additionally adapted to register a particular measurement location temperature, and to transduce such into a corresponding temperature measurement signal, namely an electrical measurement signal representing the particular measurement location temperature.

Abstract translation: 换能器装置包括换能器壳体，管，温度传感器以及温度传感器。 该管被布置在换能器壳体的空腔内，使得在面向空腔内表面的换能器壳体的壁与面向空腔的管壁的外表面之间形成中间空间。 此外，管适于在其内腔中引导流体，使得面向腔的管壁的内表面与在内腔中引导的流体接触。 每个温度传感器通过布置在中间空间内的温度检测器以及通过将相应的温度检测器与管的壁热传导耦合的耦合体来形成，并且另外适用于将特定的测量位置 温度，并将其转换成相应的温​​度测量信号，即表示特定测量位置温度的电测量信号。
