Temperature switches play a crucial role in temperature control systems in numerous industrial fields and daily life. They can automatically turn on or off circuits based on preset temperature values, precisely regulating the temperature to ensure the normal operation of equipment and the stability and safety of production processes. However, with the passage of time and the influence of environmental factors, the performance of temperature switches may deviate. Uncalibrated temperature switches may not trigger actions at accurate temperature points, which will lead to overheating or overcooling of equipment, resulting in a series of problems such as reduced production efficiency, damaged product quality, and even equipment failure and shutdown. Therefore, regular calibration of temperature switches is of great significance. It not only maintains the accuracy of temperature control systems but is also a necessary measure to ensure the reliable operation of the entire operating system, saving enterprises a lot of potential maintenance costs and production losses.
