The control system of a tunnel oven typically utilizes a computer system or a Programmable Logic Controller (PLC) for fully automated monitoring. The system enables multi-zone, independent PID temperature control, ensuring uniform and stable temperatures within the oven.
Monitored parameters encompass key process variables-such as zone temperatures, conveyor belt speed, internal oven pressure, and the pressure differential across high-efficiency filters-and the system includes alarm functions. Furthermore, modern control systems can integrate online particle monitoring to continuously track airborne particle counts in critical areas (such as the cooling zone) and trigger alarms if limits are exceeded. Centralized monitoring and data management for multiple oven units can be achieved via communication methods such as Ethernet.
