Ceramic Sheath R Type and S Type High Temperature Thermocouple

A. Product Overview

Ceramic Sheath R Type and S Type High Temperature Thermocouple is a premium temperature sensor used for measuring very high temperatures in industrial processes. It is suitable for applications where normal metal sheath thermocouples may not survive due to extreme heat.

R Type and S Type thermocouples are made using platinum and platinum rhodium alloy wires. These materials provide stable temperature measurement at high temperatures and are widely used in critical heating applications.

The ceramic sheath acts as a protective covering around the thermocouple element. It helps protect the sensor from direct heat, oxidation, contamination and harsh furnace environments. These thermocouples are commonly used in furnaces, kilns, boilers, heat treatment plants, laboratories, metalworking industries and manufacturing units.

B. Working Principle

A thermocouple works on the principle of voltage generation between two different metal wires. When the measuring junction is exposed to heat, it generates a small voltage. This voltage changes according to the temperature.

In an R Type or S Type thermocouple, platinum and platinum rhodium alloy wires are joined at the sensing end. When this sensing end is placed inside a furnace, kiln or high temperature process area, the thermocouple generates a signal based on the process temperature.

This signal is then sent to a temperature indicator, controller, recorder or automation system. The ceramic sheath protects the sensing element and allows the thermocouple to measure temperature safely in high heat applications.

C. Why It Is Used

Ceramic Sheath R Type and S Type High Temperature Thermocouples are used where accurate and stable temperature measurement is required at very high temperatures.

They are used because they offer:

• Reliable temperature measurement in high temperature applications
• Better stability compared to standard base metal thermocouples
• Protection from oxidation and harsh furnace conditions
• Suitable performance in furnace, kiln and heat treatment applications
• Long service life when properly installed and maintained
• Accurate temperature monitoring for process quality and safety

In industries like metalworking, aerospace, glass, ceramics and manufacturing, temperature control is directly connected to product quality. This thermocouple helps maintain correct process temperature and supports consistent output.
