Temperature
Temperature directly affects quality, safety and costs in multiple processes. In food production and packaging, for instance, the correct temperature is crucial to product quality and to preventing contamination. The temperature of perishable foods and substances used in the pharmaceutical industry has to be carefully recorded during storage and transport to ensure product safety.
Temperature is also an essential factor in processes where chemical reactions are necessary or where they actually have to be prevented. In this regard, the line between a chemical reaction and the absence of one is often extremely thin. Accurate temperature measurement is important not only for quality and safety, but also as regards cost. Consider a blast furnace, for instance. The temperature must be high enough to produce high-quality steel, but it is also expensive to maintain the temperature at 5°C above the required process temperature all the time.
