PhoenixTM supplied a hot-box system capable of monitoring temperature through low-pressure carburizing furnaces with integrated oil quench to a furnace manufacturer in Japan. The data logger monitors part temperature via type-K thermocouples. It is able to follow the parts throughout the entire process, including the low-pressure carburizing cycle, the oil quench and the subsequent wash cycle. The system will be used primarily for the installation of new furnaces supplied by the manufacturer and ongoing research into new furnace designs. The PTM1000 series data logger at the heart of the system maintains an accuracy of +/-0.3°C and allows detailed thermal analysis of the actual temperature profile throughout the cycle.
