A housing module includes a housing including a housing wall, a first housing chamber and a second housing chamber separated by a partition wall, wherein: the partition wall has a through-opening for an electrical feedthrough for connecting measurement/operating electronics to interface electronics; the feedthrough satisfying requirements of an Ex-d standard; the feedthrough having an electrically insulating carrier body and a plurality of electrically conductive connecting devices for providing the electrical connection, which connecting devices extend through holes in the carrier body; the holes each having a first dimension along a hole axis and each having an inner diameter; the connecting devices each having an outer diameter; the carrier body being inserted into the through-opening from a side of the partition wall facing the first housing chamber, and forming a flame arrestor according to the Ex-d standard.

Housing module and field device

A housing module of a field device includes: a housing including a first housing chamber and a second housing chamber separated by a partition wall; measurement/control electronics disposed in the first housing chamber; interface electronics for connecting lines for supplying energy to the field device arranged in the second housing chamber, wherein the housing includes a first wall region to receive the partition wall, the first wall region separated from the partition wall by a gap having a path length, wherein the ratio of a gap width to the path length is less than 0.02; and a securing device for limiting a range of movement of the partition wall toward the second housing chamber, wherein the housing includes a second wall region with a groove extending parallel to a cross-sectional plane of the partition wall, the securing device including an engagement device to engage in the groove.

A field device of measuring- and automation technology, which field device meets requirements for operation in explosion-endangered environments. Safe operation of the field device in explosion-endangered environments is assured by a pluggable connector coupling for electrical coupling of different field device components. An essential feature of the pluggable connector coupling is a sealing element for spatial and gas-tight sealing of a contact region of contacting elements of the pluggable connector coupling from a free volume remaining in the pluggable connector coupling.

Field device of measuring- and automation technology

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.
