Why Use Sheathed Type S Thermocouples in Metal Processing?

Mar 07, 2025

Sheathed Type S Thermocouples are high-precision, high-temperature-resistant temperature sensors widely used in metal processing equipment to ensure accurate temperature control and process stability. Below are the main applications of Sheathed Type S Thermocouples in metal processing equipment:

Thermocouple-5

1. Temperature Monitoring in Melting Furnaces

Application Scenario: In metal melting furnaces, Sheathed Type S Thermocouples can be directly inserted into molten metal or the furnace chamber to monitor the melting temperature in real time.

Advantages: Their high-temperature resistance (up to 1600°C) and fast response characteristics ensure precise temperature control during the melting process, preventing overheating or insufficient temperature.

 

2.Temperature Control in Heat Treatment Furnaces

Application Scenario: In processes such as annealing, quenching, and tempering, Sheathed Type S Thermocouples are used to monitor furnace temperatures, ensuring that metal materials achieve the desired physical properties.

Advantages: High-precision measurement and long-term stability help improve the consistency of heat treatment processes and product quality.

 

3. Temperature Monitoring in Casting Equipment

Application Scenario: During casting, Sheathed Type S Thermocouples can be installed in molds or pouring systems to monitor the temperature of molten metal.

Advantages: Their sheathed structure can withstand high temperatures and mechanical shocks, ensuring stable operation in harsh environments.

 

4. Temperature Management in Rolling and Forging Equipment

Application Scenario: During rolling or forging processes, Sheathed Type S Thermocouples can be embedded in rolls or dies to monitor the temperature of metal workpieces in real time.

Advantages: Fast response and wear-resistant properties ensure precise temperature control during high-speed rolling or forging processes.

 

5. Temperature Monitoring in Welding Equipment

Application Scenario: In processes such as laser welding and arc welding, Sheathed Type S Thermocouples can be used to monitor the temperature of the welding zone.

Advantages: High-precision measurement helps optimize welding parameters, improving welding quality and efficiency.

 

6. Temperature Control in Induction Heating Equipment

Application Scenario: In induction heating equipment, Sheathed Type S Thermocouples can be installed near heating coils to monitor workpiece temperature.

Advantages: Their high-temperature resistance and anti-electromagnetic interference capabilities ensure stable operation in induction heating environments.
