Performance Characteristics of Type K Thermocouples Across Different Temperature Ranges
🔹 1. Low Temperature Range (−200°C to 0°C) • Electron Migration is Suppressed At cryogenic temperatures, atomic thermal motion weakens, reducing the ease of electron migration from the Nickel-Chromium leg to the Nickel-Silicon leg. This leads to lower thermoelectric EMF output and reduced sensitivity. • Increased Electrical Resistance As temperature decreases, the electrical resistance of […]
