Abstract

The invention relates to a measuring device for measuring the temperature in a reactor container which can be crossflown by bulk material, in particular in a solid phase polycondensation, which takes place in an SSP-reactor. The aim of the invention is to protect the measuring device against mechanical stresses. Said aim is achieved by virtue of the fact that the measuring device, which is used to measure temperature, comprises at least one metal profile, at least one measuring tube and at least one sensor which is arranged therein. The metal profile can be connected to the walls of the reactor container and the measuring tube is connected to the metal profile such that it is partially reinforced on the external wall thereof by means of the metal profile. As a result, the measuring tube is soldered, screwed, riveted or rigidly connected in another manner to the metal profile. The metal profile is then secured to the inner wall of the reactor container. Another advantage thereof is that the weight, which is exerted on the column of the bulk material, is partially applied to the SSP reactors which are equipped with the measuring devices.
