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.

Abstract: A conveyor belt for pipe conveyors is indicated which includes overlapping of the conveyor belt at the edges when the belt pipe is formed and which consists of rubber or rubber-like plastic material and a plurality of steel ropes, all being alike, embedded therein as tension carriers and extending in longitudinal direction of the conveyor belt. They all have the same mutual spacing in transverse direction of the conveyor belt and are especially rich in elongation. At the runing side of the conveyor belt a continuous, transversely stiff insert is provided in addition, it extends across the full width of the conveyor belt and comprises steel cords oriented in transverse direction. Another transversely stiff, textile insert is provided in addition at the supporting side of the conveyor belt, yet it is not located in the two edge regions of the conveyor belt which overlap when the belt pipe is formed.
