Abstract

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.
