Abstract
A pressure-tight encapsulated housing () having a temperature control device () including a first heat exchanger unit () arranged in the interior of the housing () and a second heat exchanger unit () arranged outside of the housing () and which are connected to one another via a liquid cycle (). The liquid cycle () includes a feed line () and a return line () each connected to the first heat exchanger unit () and which each fluidically connect to a passage channel () of a respective leadthrough unit () arranged in flameproof manner in a wall () of the housing () so that the passage channel () extends through the wall (). The control device () further includes a liquid monitoring sensor () for generating a liquid monitoring signal (F) characteristic of the filling of the passage channels () with liquid, and a monitoring unit () for receiving signals generated by the liquid monitoring sensor ().
