In the huge and complex field of industry, temperature measurement is like a nervous system, running through every production link and playing a decisive role in production stability, efficiency and product quality.
In the chemical production field, the accuracy of temperature measurement is directly related to the process and results of chemical reactions. Taking the ammonia synthesis industry as an example, nitrogen and hydrogen react to form ammonia under high temperature, high pressure and the action of a catalyst. This reaction has extremely strict requirements for temperature. The reaction temperature is usually around 400 - 500℃. If the temperature is too high, not only will the reaction rate be too fast, leading to out-of-control reactions, but it may also cause side reactions and reduce the yield and purity of ammonia. If the temperature is too low, the reaction rate will be too slow and affect production efficiency. Therefore, chemical enterprises install high-precision temperature sensors and control systems in reaction kettles to monitor and adjust the temperature in real time to ensure that the reaction proceeds under the optimal temperature conditions. Similarly, in different chemical processes such as cracking reactions and polymerization reactions in the petrochemical industry, accurate temperature measurement is essential to ensure product quality and production safety.
The energy production industry is also inseparable from temperature measurement. In thermal power plants, boilers are core equipment, and the steam temperature inside is a key parameter. High-temperature and high-pressure steam drives the turbine to rotate and then drives the generator to generate electricity. The measurement and control of steam temperature are crucial for power generation efficiency and equipment safety. Generally speaking, the main steam temperature of subcritical units is around 540℃, and the steam temperature of supercritical units is even higher. By installing temperature measuring equipment such as thermocouples at various key parts of the boiler, engineers can obtain steam temperature information in real time and adjust operation parameters such as the combustion process and feed water flow according to these data to ensure that the steam temperature is stable within the design range, prevent safety accidents such as pipeline rupture and turbine blade damage due to excessive temperature, and improve power generation efficiency.
In the manufacturing industry, whether it is metal processing or electronic component manufacturing, temperature measurement has an indispensable position. In the heat treatment process of metal processing, such as quenching and tempering processes, different metal materials need to be processed within a specific temperature range to modify its organization and properties. For example, when high-carbon steel is quenched, the heating temperature is generally between 760 - 820℃. Accurate temperature control can give the steel the ideal hardness and toughness. In electronic component manufacturing, chip manufacturing is a process with extremely high temperature requirements. From the growth of silicon wafers, lithography, etching to doping and other steps, they all need to be carried out in a constant temperature environment. The temperature fluctuation must be controlled within a very small range. This requires advanced temperature measurement technology and high-precision temperature control equipment to ensure that each chip can meet strict quality standards.
