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.

The invention relates to a field device of measuring and automation technology. The field device has a radio module for providing access to an operating electronics of the field device. Such access enables the exchange of information between the operating electronics and a user. The radio module can be turned on by a first input signal sequence composed of accelerations of the field device housing and can be turned off by a second input signal sequence. A field device of the invention is shown schematically in FIG.

An interface between a sensor unit and an explosion resistant housing, wherein arranged in the explosion resistant housing is a measurement amplifier. In the interface, which is simply manufacturable and, despite that, meets the requirements of explosion protection, the measurement amplifier is arranged on a plug unit formed in the sensor unit and preferably protruding inwardly into the explosion resistant housing.

The electronic apparatus ( ) has an enclosure ( ), which has a terminal compartment ( ) and an electronics compartment ( ). These two compartments are separated by an internal wall ( ) which has a longitudinal slot ( ) of depth T in which a bushing ( ) is fitted. The bushing is to be flameproof designed. To this the enclosure ( ) comprises: 1) A baseboard ( ) which extends into and is mounted in the electronics compartment, has a stop ( ), and can be fitted with electronic components ( ); 2) a lead arrangement ( ) extending into the terminal compartment ( ) and contacting the components on the baseboard; and 3) a plastic part ( ) which surrounds the lead arrangement, is formed integrally with the stop ( ), and has the shape of, and thus fills, the longitudinal slot ( ).
