Are All K-Type Thermocouples the Same? Why Not?
No, not all K-type thermocouples are the same. Although they are all called “K-type” (meaning they share the same nickel‑chromium / nickel‑silicon alloy material system), in real‑world applications they differ greatly in accuracy class, sheath structure, material details, application environment, and calibration standards. Simply put: “K-type” only defines the thermoelectric …Read more -
What types of high-temperature thermocouples are there? What are their characteristics and functions?
High-temperature resistant thermocouples are core temperature-sensing elements used in industry for measuring high-temperature media. Their typical continuous operating temperature exceeds 800℃, and some special models can measure ultra-high temperatures above 1800℃. Based on the Seebeck effect, they convert temperature signals into thermoelectric voltage signals, suitable for high-temperature applications such as …Read more -
