In: III CIIC 2014, 2014, Manaus. Anais... Manaus: UFPA, 2014.https://rigalileo.itegam.org.br/handle/123456789/1060The study presents the implementation of a digital temperature control system based on hysteresis to optimize energy efficiency in a plastic injection industry. The results demonstrate a significant reduction in energy consumption, with annual savings of approximately R$ 47,166.86, along with improvements in temperature stability, reduced maintenance costs, and extended equipment lifespan. The system proved economically viable, with a return on investment in 39 days.pdf.Sistema de ControleEficiência EnergéticaControlador de HistereseTemperatura DigitalIndústriaArtigoEngenharia Elétrica
