High Temperature Noble Metal Thermocouple
Product Overview
Section titled “Product Overview”The high temperature noble metal thermocouple is suitable for high-temperature applications in a variety of production processes. It is widely used for temperature measurement in glass, ceramics and industrial salt bath furnaces.
Applications
Section titled “Applications”- High-temperature measurement in the glass industry.
- High-temperature measurement in the ceramic industry.
- Industrial salt bath furnace temperature measurement.
- Other high-temperature production-process applications.
Product Advantages
Section titled “Product Advantages”- S, R and B graduations are available.
- The temperature measurement range is 0 to 1300°C for S and R graduations, and 0 to 1600°C for B graduation.
- High-alumina corundum protective tube material.
- Thermal response time for the Φ16 mm specification is less than 150 s.
- Junction box protection level is IP65.
Installation Method
Section titled “Installation Method”The structure diagrams show different protective-tube constructions. For selection, provide the required insertion length L, mounting dimensions, protective-tube outside diameter d and electrical-interface requirement.
