During the operation of the experimental furnace, the overheat protection system is like a loyal guard, always guarding the safety of the equipment and experiments. It cooperates with the conventional temperature control system but operates independently to ensure the smooth progress of the experiment.
The conventional temperature control system is mainly responsible for accurately adjusting the heating power of the experimental furnace according to the set temperature curve to achieve accurate control of the temperature in the furnace and meet the temperature conditions required by various experiments. The overheat protection system focuses on monitoring the abnormal rise of the temperature in the furnace, and its working principle is ingenious. It is equipped with independent high-precision temperature sensors, which are distributed in key parts of the furnace body and can sense temperature changes in real time and accurately. When the temperature in the furnace exceeds the preset safety threshold due to some reason (such as control system failure, heating element abnormality, etc.), the overheat protection system will start quickly.
Once the overheat protection system is triggered, it will immediately cut off the power supply to the heating element to prevent the temperature from rising further from the root. At the same time, it will start the corresponding cooling mechanism, such as turning on the forced air cooling device or water cooling circulation system, to speed up the heat dissipation of the furnace and make the temperature fall back to the safe range as soon as possible. Unlike conventional temperature control systems, the decision-making and execution of the overheat protection system are not restricted by conventional temperature control procedures. It acts independently according to its own safety standards to ensure that it can respond as quickly as possible in an emergency to avoid serious consequences such as damage to experimental samples, damage to the furnace structure and even fire caused by temperature out of control.
This independence is also reflected in its independent alarm function. When the overheat protection system is activated, a striking alarm signal will be issued synchronously to remind the operator to pay attention to the equipment status in time and take necessary countermeasures. Through separation and cooperation with conventional temperature control systems, the overheat protection system of the experimental furnace provides reliable safety redundancy for scientific experiments, allowing researchers to explore the unknown in a safe and stable environment and promote the continuous development of scientific research.
