How to Extend Thermocouple Lifespan in High-Temperature Environments
Thermocouples are essential tools in high-temperature industrial applications, providing accurate temperature measurements critical for process control and safety. However, their lifespan can be significantly affected by harsh operating conditions. This article explores strategies to extend the lifespan of thermocouples in high-temperature environments, supported by industry case studies and insights. Understanding Thermocouple Degradation Mechanisms Thermocouples operate based on the Seebeck effect, where two dissimilar metals produce a voltage proportional to temperature differences. In high-temperature settings, several degradation mechanisms can impair their performance: Oxidation and Corrosion: Exposure to oxidizing atmospheres can deteriorate thermocouple materials, leading to measurement inaccuracies. Drift: Prolonged exposure to
