Threaded Type K Thermocouple

The threaded K-type thermocouple is a standardized temperature measurement element developed based on K-type thermocouple technology. It uses nickel-chromium-nickel-silicon (nickel-aluminum) alloy as the thermoelectric electrode material, with the positive electrode (KP) being nickel-chromium alloy and the negative electrode (KN) being nickel-silicon alloy. The product can be quickly and stably installed through standard threaded interfaces (such as M12×1.5, NPT1/2, etc.), and can be closely embedded into the temperature measurement holes of equipment pipelines, reaction vessels and other containers. It can accurately capture temperature changes and convert them into millivolt-level thermoelectric potential signals for output, providing reliable data support for temperature monitoring and control.

Product Advantages
Efficient installation: The standard threaded interface design enables quick screwing into the preset installation holes of the equipment without the need for complex tools or additional accessories, significantly reducing installation time. It is particularly suitable for scenarios that require frequent disassembly, assembly, and maintenance.
 ​
Wide temperature range measurement: The temperature measurement range is -200 ℃ to 1300℃, which can not only meet the low-temperature measurement requirements of cryogenic processes, but also be applicable to high-temperature smelting, heat treatment and other industrial high-temperature links.
 ​
High cost performance: Compared with precious metal thermocouples, the alloy materials used have a lower cost and excellent thermoelectric performance. They can achieve high-precision measurement at a lower cost in the field of medium and low temperature measurement. 
​
Strong anti-interference: It has a strong resistance to electromagnetic interference, environmental vibration and other interference factors. Even in complex industrial electromagnetic environments and highly vibrating equipment, it can still stably output accurate temperature signals. 
​
Wide compatibility: It complies with the internationally recognized K-type thermocouple calibration standards and can be seamlessly integrated with various K-type temperature transmitters, display instruments, and data acquisition systems, facilitating system integration and equipment upgrading and transformation.
