SYSTEME DE REGULATION THERMIQUE D'UNE PLURALITE DE FOURS ELECTRIQUES

摘要

The control circuit includes a resistance heater in series with a controlling thyristor and a voltage divider or controlling the oven temp. The output from the voltage divider is fed to a differential amplifier which excites a pulse generator to feed pulse signals via an 'and' gate to the controlling thyristor so that the thyristor is activated to supply current to the resistance heater. The ovens are used for heat treating synthetic textiles and their temps. can be accurately controlled.
