What can be installed between protective linings and structural elements to monitor temperatures?

Thermocouples are electronic devices that consist of two dissimilar conductors joined at one end, which produce a voltage that corresponds to temperature changes. When installed between protective linings and structural elements, thermocouples can effectively monitor temperatures in those specific environments. They are widely used in industrial applications due to their accuracy, durability, and ability to operate over a broad temperature range.

Unlike simple thermometers, which may not provide the detailed data needed for rigorous monitoring, or infrared (IR) cameras, which measure surface temperatures and could be influenced by environmental factors, thermocouples provide direct temperature readings from within the material or structure. This allows for more reliable monitoring of temperature variations that could indicate potential failure points or the effectiveness of protective measures. Additionally, temperature sensors as a broader category could include various types, but thermocouples are particularly effective for applications requiring precise measurement in the context mentioned in the question.
