TEMPERATURE MEASUREMENT IN A HEAT WELDING SYSTEM

摘要

The invention relates to a method for measuring the temperature (T) of a heating element used in a heat welding system (200) during a welding cycle, wherein said method comprises: a preliminary calibration step that consists of measuring the initial temperature (T0) in absolute value of said heating element; a step of applying a voltage in order to modify the temperature of said heating element; at least one step of measuring an electric variable G(?T) based on the temperature variation (?T) of said heating element; and a step of determining the temperature T (?T, T0) of the heating element from the measured value of the variable G(?T) and the initial temperature (T0).
