Abstract

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.
