Abstract

A probe tube which is introduced into a reaction container for measuring the operating condition of a medium in the interior of the container has a first seal which is resistant to temperature and a second seal which is resistant to pressure and gas-tight. Those seal respectively close the inner and outer ends of the probe tube. The interior of the probe tube communications with the interior of the reaction container by way of an opening, whereby the temperature-resistant seal at the tip of the probe tube is relieved of the loading of pressure forces.
