    Abstract: A pressure resistant adapter, for connecting a transmission line to a field device has a shell, insertable into a wall of a housing of the field device. The shell has an interior open to an interior of the housing and closed to the exterior by an end wall of the shell. An insert, installed in the shell, includes a base element and a projection protruding out of the shell through an opening in the end wall of the shell. The base element has a basal area greater than a basal area of the opening. A connection element is provided on an end of the projection protruding out from the shell, to which the transmission line is connectable, and at least one conductor extends through a window that is located in the base element adjoining the bore in the projection and opens to the interior of the housing.

    Abstract: A circuit for signal transfer and galvanic isolation between first and second digital signal processing units, wherein a first signal path is provided between the first and second signal processing units. The first signal path has a first section, which includes positive and negative signal lines and serves for transfer of a differential signal between the first and second signal processing units. At least one capacitor is provided in the positive signal line and at least one capacitor in the negative signal line. The capacitors serve for galvanic isolation between the first signal processing unit and the second signal processing unit, and the capacitors are embodied, in each case, according to the specifications of the ignition protection type, intrinsic safety.

    Abstract: A pressure resistant adapter, for connecting a transmission line to a field device, comprising, insertable into an opening in a housing wall of a housing of the field device, a shell, which in the assembled state has an interior open to an interior of the housing and closed to the exterior by an end wall of the shell, installed in the shell, an insert, which includes a base element arranged in the shell and a projection protruding out of the shell through an opening in the end wall of the shell. The base element has a basal area, which is greater than a basal area of the opening in the end wall of the shell, a connection element, which is provided on an end of the projection protruding out from the shell and to which the transmission line is connectable, extending through a bore in the projection and connected to a connection contact of the connection element, at least one conductor, which extends through a window, which is located in the base element adjoining the bore in the projection and which is open to the interior of the housing, and a potting compound, which fills hollow space remaining in the shell.
