A Novel Application of Multipoint Temperature Control Using PID

This paper presents a novel technique of multipoint temperature control employing the PID. This technique serves to enhance the efficiency and performance of heaters. In industry the Heater plays a significant role. For instance, in a big industry such as cement industry requiring furnaces, the heater supplies the heating. The industry uses a huge number of heaters for various purposes. In the ancient method of heating, the many number of heaters used to be connected and individual power supply was required for each heater. But in the proposed new technique presented in this paper, a number of heaters work on the supply of a single heater power employing the time sharing mode. Here, heaters turn ON and OFF as per the set point, conserving power and lessening heat loss. And to achieve this, our proposed technique of multipoint temperature control using the PID is advanced. Thus, this project focuses on the scenario where a number of heaters are connected and constant temperature is being controlled as per the desired value (set point) in a closed loop through the use of PID controller system. The PID controller is set up to monitor and regulate the heating systems and to maintain optimum temperature. It also ensures minimum heat loss and low power consumption, thus saving power. The heating control application of the PID controller uses thermocouple as a sensing element and a feedback system to the PID controller. This project uses themocouple for detecting the temperature of the closed loops. The technique achieves precise temperature control. Thus, this project introduces a new innovation relating to the proposed topic and system, which is based on multiple temperature control and is applicable in industries where heaters are essential. The related Hardware has been successfully designed and tested.
