Ceramic Thermocouples

Ceramic thermocouples are commonly used in industrial applications that involve high temperatures and harsh environments.

Some of the main uses of ceramic thermocouples include:

High-Temperature Processes:

Ceramic thermocouples are employed in various high-temperature processes for temperature monitoring and control. Industries such as steel manufacturing, glass production, kilns, incinerators, and cement production rely on ceramic thermocouples to accurately measure temperatures in their operations.

Heat Treatment

Ceramic thermocouples are used in heat treatment processes, including annealing, hardening, tempering, and stress relieving. They help ensure precise temperature control and uniform heating or cooling of the materials being treated.

Semiconductor Manufacturing

Ceramic thermocouples are used in the semiconductor industry for temperature monitoring during processes like wafer fabrication, sputtering, and thermal treatment. They help maintain precise temperature control during semiconductor manufacturing.

Research and Development

Ceramic thermocouples are used in various research and development activities across industries. They find applications in specialized experiments, test setups, and equipment that require accurate temperature measurement in demanding environments.

There are three common types of ceramic thermocouples we provide, each with unique properties. They are R, S, B Type.

R-Type Thermocouple

Type R (PtRh13/Pt): Type R ceramic thermocouples are made with platinum-rhodium alloys. They are suitable for high-temperature applications, with a temperature range typically up to 1600°C. They offer excellent stability and accuracy.

S-Type Thermocouple

Type S (PtRh10/Pt): Type S ceramic thermocouples also use platinum-rhodium alloys. They have a similar temperature range as Type R (up to 1600°C) and are commonly used in high-temperature applications requiring high accuracy.

B-Type Thermocouple

Type B (PtRh30/PtRh6): Type B ceramic thermocouples utilize platinum-rhodium alloys and have a temperature range up to 1700°C. They are suitable for ultra-high-temperature applications, but they require careful handling due to their delicate nature.

1.Ceramic thermocouples are designed to withstand extremely high temperatures, typically ranging from several hundred degrees Celsius up to 2300°C, depending on the type. They maintain their accuracy and reliability even in demanding industrial processes with elevated temperatures.
2. Ceramic sheaths surrounding the thermocouple wires provide excellent mechanical protection. They help shield the thermocouple from physical damage, abrasion, and chemical exposure, making ceramic thermocouples suitable for rugged environments.

Ceramic thermocouples are typically made using a combination of different materials to create a temperature sensor.The base material for ceramic thermocouples is usually a ceramic insulator. Common ceramic materials used include alumina (Al2O3), mullite, or silicon nitride (Si3N4). These ceramics provide good electrical insulation and high-temperature stability.
