Industrial K type assembly water-proof thermocouple with thermowell
Origin: Thermocouples are the most commonly used thermometer, they are electrical circuits made up of two different metal conductors, and they have different performance properties due to different materials and structure. The temperature measurement of thermocouple is based on the thermoelectric effect discovered by Seebeck.
Standardization:The thermocouple is interchangeable and universal through standardization, which promotes the continuous development of thermocouple manufacturing and practical technology. Since 1985, China has provided for seven standard thermocouples of K,E,J,T,S,R and B, according to ITS_68 international practical temperature scale. Since 1987,N thermocouples have been added according to ITS-90 international practical temperature scale and IEC 584-95 international standards.
