Abstract
A temperature sensor for mixing and kneading vessels, particularly for rubber kneaders, which is sealingly mounted in an opening in a housing wall of the vessel to project into the material to be mixed and/or kneaded. A thermocouple is mounted in the measurement tip for transducing measured temperature into signals transferred to a measurement device. The measurement tip comprises a thin-walled tube of relatively large diameter made of high-strength low heat-conductivity material. The tube has a conical portion at the tip end of which is mounted a high heat-conductivity material connected to the thermocouple. The outer surface of tube is coated with an insulation layer of ceramic at least in the region in which the tube is engaged in the housing wall.
