1. An apparatus for monitoring a power capacitor having a housing with a housing interior configured to be closed off in a gas-tight manner at at least one housing opening, the apparatus comprising:
at least one sensor device outputting a signal as a function of a gas pressure in the housing;
an adapter mechanically connecting said sensor device to the housing at the at least one housing opening and fluidically connecting said sensor device to the housing interior;
said adapter having a cylindrical adapter body divided into a plurality of functional longitudinal sections and a feed-through for the fluidic connection extending over said plurality of longitudinal sections, said adapter body having a longitudinal axis;
said plurality of longitudinal sections including a first longitudinal section to be disposed in a region of the at least one housing opening after connecting said adapter to the housing, said first longitudinal section closing off said feed-through in a plane perpendicular to said longitudinal axis and fluidically connecting said feed-through to the housing interior in at least one plane parallel to said longitudinal axis.
