The most commonly used high temperature thermocouples for boiler and furnace applications are Type K and Type N. Type K thermocouples are made of chromel (NiCr) and alumel (NiAl) and are suitable for use in temperatures up to 1260°C (2300°F). Type N thermocouples are made of Nicrosil (NiCrSi) and Nisil (NiSi) and can be used in temperatures up to 1260°C (2300°F).
When selecting a high temperature thermocouple for boiler and furnace applications, it is important to consider factors such as the operating temperature range, the accuracy requirements, and the environmental conditions. The thermocouple must be selected based on the specific requirements of the application to ensure accurate and reliable temperature measurements. It is also important to ensure that the thermocouple is properly installed and maintained to ensure optimal performance and longevity.
