Abstract: A measuring device for determining a process variable of a medium includes a housing comprising a housing body with an inner surface. The measuring device includes a temperature measuring apparatus comprising a first temperature sensor configured to determine a first temperature value, and an evaluation circuit configured to determine a medium temperature as a function of the first temperature value. The measuring device also includes a rigid printed circuit board having a resilient printed circuit board component. The first temperature sensor is arranged on the printed circuit board component. The printed circuit board component at least partially touches the inner surface of the housing body.

Abstract: A magnetically inductive flow measuring probe comprises a housing that is adapted to be exposed to the medium; two measuring electrodes arranged in a housing end section for forming a galvanic contact with the medium and for sensing a voltage induced in the flowing medium; and a means for producing a magnetic field passing through the housing end section. The means includes a coil arrangement and a field guide body. The field guide body comprises two field guide body legs connected with a coil core, extending to a front section of the housing and adapted to serve as field guideback. Orthogonal projections of the measuring electrodes and the field guide body onto a cross sectional plane are disjoint.
