Thermo control for ceramic firing ovens
The application collects information about the instantaneous temperature and pressure indicators from the dTRON and mTRON controllers of Jumo. The length of the furnace is 75 m, and temperature sensors are placed at different lengths. Ten zones are regulated by an atmospheric oxygen flap, and in twelve zones, intermediate temperatures are measured to draw a plot of temperature along the length of the tunnel with a total capacity of 2700 cubic meters. The communication is LON, transformed through a gateway in Modbus RTU. Trends illustrate the temperature indicators in the adjustment zones. After each trolley with products, the pressure at the entrance of a furnace changes, thus becoming known the number of trolleys entered the furnace.
