K type thermocouple is currently the largest amount of inexpensive metal thermocouples, the amount of which is the sum of other thermocouples. K-type thermocouples have the advantages of good linearity, large thermal electromotive force, high sensitivity, good stability and uniformity, strong anti-oxidation performance and low price, and can be used in an oxidizing inert atmosphere. K type thermocouple material The nominal chemical composition of the positive electrode (KP) is: Ni:Cr=90:10, and the nominal chemical composition of the negative electrode (KN) is: Ni:Si=97:3, and the use temperature is -200 ° C to 1300 ° C. K type thermocouple classification: 1, classified by assembly and structure According to the choice of K-type thermocouple protection sleeve and the choice of wiring part, K-type thermocouple can be divided into assembly thermocouple, armored thermocouple, end face thermocouple, compression spring fixed thermocouple, high temperature thermocouple, platinum-iridium thermoelectric Even, anti-corrosion thermocouple, wear-resistant thermocouple, high-voltage thermocouple, special thermocouple, hand-held thermocouple, micro thermocouple, single-core armored thermocouple and so on. 2, classified by fixed form Thermocouples are widely used as the main means of temperature measurement. Therefore, there are many requirements for fixing devices and technical performance. Therefore, thermocouple fixing devices are divided into six types: non-fixed device type, threaded type, fixed flange type, and active method. There are six types of blue, movable flange angle and tapered protection tube. K type thermocouple advantages: 1. Simple assembly and convenient replacement; 2, pressure spring type temperature sensing element, good seismic performance; 3. High measurement accuracy; 4, the measurement range is large (-200 ° C~1300° C); 5, the thermal response time is fast; 6. High mechanical strength and good pressure resistance; 7, high temperature resistance up to 1300 degrees; 8, long service life. Thermocouple protection tube material
The K type thermocouple is a temperature sensor, and the K-type thermocouple is usually used with display instruments, recording instruments and electronic regulators. K-type thermocouples usually consist of main components such as temperature sensing components, mounting fixtures and junction boxes.
