In practical selection, the following points should also be considered:
1. Identify primary requirements: If the fastest possible temperature change detection is needed (e.g., experimental research, process debugging), prioritize thinner wires. If the application environment experiences high vibration, high temperature, and requires long-term stability, thicker wires are a more reliable choice.
2. Note the relationship between temperature and diameter: Within the applicable range of type K thermocouples (typically -200℃ to 1200℃), for the same material, thicker wires generally have a higher maximum operating temperature and longer lifespan. For ultra-high temperature scenarios (e.g., approaching 1200℃), thicker wires are usually a must.
3. Consider intermediate options: Wires with a diameter of approximately 0.5mm to 1.0mm offer a balance between performance and strength, providing fast response and a certain degree of durability. They are suitable for most general industrial applications, such as small to medium-sized heating equipment and food processing machinery.
What differentiates one thermocouple from another is the metals in its two wires: the positive leg and the negative leg. Because each thermocouple type has a different pairing, they differ in temperature limits, process conditions (inert, oxidizing, reducing atmospheres, heavy vibration), and so on.
