High Temperature Ceramic Sheathed Thermocouples
These are suitable for general use and as replacement elements for industrial and high temperature thermocouples similar to our Types 13 and 14 described on pages 49 and 51. Type 2 assemblies are available for thermocouple types K, T, J, N and E with insulators in Aluminous Porcelain and for types R, S, B and C* with insulators in Recrystallised Alumina. The length of insulators is 1", 2" or 4" depending on the application and availability. Insulators with 4 bores are available for duplex applications, please contact us for further details.
* type c thermocouples can only be used where the full product is inside a process with zero oxygen

Frequently Asked Questions
- What is a thermocouple and how does it work?
A thermocouple is a type of temperature sensor that generates a voltage when two different metals are joined at one end and exposed to a temperature difference between the "hot" junction (where the temperature is measured) and the "cold" junction (the reference point). This voltage is then measured to determine the temperature at the hot junction. - How do I choose the right thermocouple for my application?
The ideal thermocouple depends on factors such as temperature range, accuracy, termination type, mounting requirements and environmental conditions. We offer a variety of thermocouples with different sheath materials, constructions, terminations, and temperature ratings to meet your needs. If you need specific advice, our engineers are happy to assist! - What is the maximum temperature rating of your thermocouples?
Our thermocouples are designed to handle a wide range of temperatures with some mineral insulated thermocouples able to withstand temperatures up to 2300ºF and ceramic sheathed thermocouples going even higher to 2900ºF. Each product listing includes the maximum temperature rating, so you can choose the best thermocouple for your application.
