Abstract

A temperature probe, particularly for thermoplastic mix extrusion machines, which comprises at least one casing, which is adapted to be inserted in an extrusion cylinder substantially at right angles to the extrusion direction with one end thereof facing into the internal cavity of the extrusion cylinder so that it is in direct contact with the extrusion material contained in the internal cavity, and at least one thermocouple, which is accommodated in the casing and is adapted to detect the temperature of the extrusion material by thermal conduction through the casing, the temperature probe comprising thermally insulating elements which are interposed at least partially between the casing and the extrusion cylinder so as to reduce the thermal influence of the extrusion cylinder on the measurement made by the thermocouple.
