High Temperature Thermocouple
High Temperature Thermocouple
Type B, R, S, C, D, G | Excessive Temperatures | Measurements up to 2300 °C | Severe Atmospheres | Carburizing | Oxidizing | Reducing | Special Limits of Error (Class 1)
ARi High Temperature Thermocouple is used in applications where base metal thermocouples cannot be used because of excessive temperatures or severe atmosphere. ARi can provide a wide variety of wire combinations and sheath materials to meet the harshest demands. By selecting certain materials, temperature measurements up to 2300°C can be achieved.
ARi manufactures it's own mineral insulated cable and many of our high temperature thermocouple are available in bendable sheath and longer lengths. This in-house capability enables us to manufacture a variety of custom material combinations. Applications include;
- Process control of vacuum furnaces
- Gas furnaces
- High temperature ovens
- Reaction furnaces
Processes include sintering, annealing and carburizing. While many process variables affect service life, there are two (2) important considerations for selecting the proper thermocouple for a particular application.
- What is the temperature range you will need to measure?
- What is the atmosphere the thermocouple will be exposed to during operation?
With this information, it is possible to use these tables to select a suitable wire, sheath and insulation combination. The physical requirements of the thermocouple (sheath diameter, junction type and termination style) can then be selected to complete the design. Of course, you can always contact our ARi sales staff for help in selecting the proper high temperature thermocouple.
