<p>The invention relates to a device which is used for the heat-sealing of a thermoplastic synthetic film to a thermoplastic synthetic container. The inventive device has at least one thermal electrode ( 11 ) which is made from a material with high thermal conductivity. The electrode is equipped with a metal section ( 30 ) having electrical connection terminals ( 31 ) at its ends. A heat flux sensor ( 32 ) comprising two electrical connections ( 33 ) is also provided, and the lower face is fixed mechanically to the upper part of the above-mentioned section ( 30 ). In addition, the upper face of the heat flux sensor ( 32 ) is fixed to the lower face of a thermal capacitor ( 34 ) which is made from a material with high thermal diffusivity and conductivity. Furthermore, a thermocouple ( 35 ) is mounted in a cavity in the metal section ( 30 ).</p> |
