Can noble metal thermocouple wire be used in extreme environments?

Noble metal thermocouple wire can be used in extreme environments to a certain extent, but there are also some limitations and requirements. Here are the details:

 

  1. High-temperature environments:
    • Advantages: Noble metal thermocouple wires are often suitable for high-temperature environments. For example, platinum-rhodium thermocouples can measure temperatures up to 1600 °C or even higher. They have excellent temperature stability and can maintain accurate measurement results in high-temperature conditions for a long time. In industries such as high-temperature smelting (e.g., steelmaking, non-ferrous metal smelting), high-temperature furnaces (e.g., ceramic kilns, industrial salt bath furnaces), and aerospace (for measuring the temperature of aircraft engine components), noble metal thermocouple wires are widely used.
    • Limitations: However, in extremely high-temperature and harsh environments for a long time, the performance of the thermocouple wire may still be affected to some extent. For example, high-temperature oxidation, corrosion by certain substances in the environment, and the influence of high-temperature radiation may reduce the service life and accuracy of the thermocouple wire.
  2. Oxidizing and inert environments:
    • Advantages: Noble metals such as platinum and rhodium have good oxidation resistance, so noble metal thermocouple wires can be used in oxidizing environments. They can accurately measure the temperature in an oxidizing atmosphere without being easily oxidized and affected, ensuring the stability and reliability of temperature measurement. In some inert gas environments or environments with relatively stable chemical properties, noble metal thermocouple wires can also play a good role in temperature measurement.
    • Limitations: But in some strong oxidizing environments with high concentrations of oxidants or complex chemical compositions, the thermocouple wire may still be subject to certain chemical attacks, affecting its performance and accuracy.
  3. Harsh mechanical environments:
    • Advantages: Some noble metal thermocouple wires are designed with special protection structures, such as ceramic protective tubes, which can provide certain protection for the thermocouple wire in harsh mechanical environments. This enables them to withstand vibrations, impacts, and abrasions to a certain extent, ensuring the normal operation of temperature measurement in such environments.
    • Limitations: However, if the mechanical impact and vibration are too severe, the thermocouple wire may still be damaged, resulting in measurement errors or even failure of the thermocouple.

Applications:

Noble metal thermocouple wire has the following applications:
 
  1. High-temperature processing industries:
    • Glass manufacturing: In the glass production process, the temperature control is crucial for ensuring the quality of the glass. Noble metal thermocouple wires can accurately measure the high temperatures in glass melting furnaces, annealing furnaces, and other equipment to help operators adjust the production process and ensure the quality of the glass products.
    • Ceramic firing: During the ceramic firing process, different temperatures are required in different stages. Noble metal thermocouple wires can withstand the high temperatures in ceramic kilns and provide accurate temperature measurements, which is beneficial to the control of the firing process and the improvement of the quality of ceramic products.
    • Heat treatment: In the heat treatment of metals, such as quenching, tempering, and annealing, the temperature is a key factor affecting the performance of the metal. Noble metal thermocouple wires can be used to measure the temperature in heat treatment furnaces to ensure the accuracy of the heat treatment process.
  2. Oxidation environments: In environments where oxidation is a concern, such as furnaces, reactors, and exhaust systems, noble metal thermocouple wires have excellent oxidation resistance and can maintain stable performance for a long time. For example, in industrial furnaces that operate at high temperatures and in oxidative atmospheres, noble metal thermocouple wires can accurately measure the temperature to help control the combustion process and ensure the safety and efficiency of the production process.
  3. Chemical processing industries: Industries relying on chemical processes, including the petrochemical, pharmaceutical, and power generation industries, often involve complex chemical reactions and high-temperature environments. Noble metal thermocouple wires offer superior chemical stability and can accurately measure the temperature in chemical reactors, distillation columns, and other equipment, which is beneficial to the control of the chemical reaction process and the improvement of product quality.
  4. Research and development: Due to their high accuracy and wide operating temperature range, noble metal thermocouple wires are valuable tools in research and development applications involving extreme temperatures. In scientific research institutions and laboratories, they are used to measure the temperature in various high-temperature experiments and research projects, providing accurate temperature data for scientific research.
  5. Aerospace and aviation fields: In the aerospace and aviation industries, high-temperature environments are common during the operation of aircraft engines and rocket engines. Noble metal thermocouple wires can be used to measure the temperature of these high-temperature components to monitor the operating status of the engines and ensure the safety and reliability of flight.
