Abstract

Изобретение касается способа управления температурой для запаивающих устройств, используемых в упаковочной промышленности, которые обеспечены электрически нагреваемыми элементами, сделанными из материала с зависимым от температуры сопротивлением. Электрический ток делится на импульсы, благодаря чему длительность импульсов устанавливается с помощью управляемого коммутатора (6). Во время перерывов между упомянутыми импульсами тока генерируются отдельные импульсы тока измерения постоянной и известной величины, и эти импульсы вызывают падение электрического напряжения на резистивном элементе (2). Упомянутое падение напряжения оказывается пропорциональным температуре резистивного элемента. Падение напряжения в регуляторе (7) сравнивается с опорным потенциалом, соответствующим требуемой температуре, благодаря чему считанная разность потенциалов между измеренным падением напряжения и опорным значением потенциала приспособлена для управления устройством возбуждения (9), которое управляет длительностью импульсов образующего тепло тока.The invention relates to a method of temperature control for soldering devices used in the packaging industry, which are provided with electrically heated elements made of a material with temperature-dependent resistance. The electric current is divided into pulses, so that the duration of the pulses is set using a controlled switch (6). During the breaks between the current pulses, separate current pulses of constant and known magnitude measurements are generated, and these pulses cause a drop in the electrical voltage across the resistive element (2). Said voltage drop is proportional to the temperature of the resistive element. The voltage drop in the regulator (7) is compared with the reference potential corresponding to the required temperature, so that the potential difference between the measured voltage drop and the potential reference value is adapted to control the excitation device (9), which controls the duration of the pulses of the heat generating current.
