High-Temperature Thermocouples, Instrumentation and Industrial Sensors

A noble metal thermocouple is designed to measure high temperatures in extreme conditions. They are made from a combination of noble metals, such as platinum and rhodium, which have high melting points and are resistant to degradation at high temperatures. Noble metal thermocouples are commonly used in industries such as aerospace, metallurgy, and petrochemical processing, where high-temperature measurements are essential for process control and safety. They are particularly useful for applications that require accuracy and stability at high temperatures, as well as in environments where other types of thermocouples may be prone to failure due to corrosion or oxidation.

A platinum thermocouple is commonly used in high-temperature applications. Platinum thermocouples are made up of a combination of platinum and another metal, typically rhodium or tungsten, which are joined at one end to create a sensing junction. One of the key advantages of platinum thermocouples is their high accuracy and stability. They are able to measure temperatures up to 1800°C with a high degree of precision, making them ideal for applications where temperature control is critical.

A custom thermocouple is a precision-engineered sensor designed for specialized industrial applications. These devices are built using dissimilar metals to create an accurate voltage signal based on temperature changes.
