The main characteristic of K type thermocouple1

K type thermocouple stable performance, high accuracy, long service life, is a kind of industrial production with commonly used to temperature measurement sensor, engineering detailed introduce for everybody below the six major characteristics of K type thermocouple.

1, the K type thermocouple for continuous use in oxidizing and inert atmosphere. Short-term use temperature is 1200 ℃, the long-term use of temperature is 1000 ℃.

2, after choosing high quality K type thermocouple can be used as a standard, to use nickel chrome - indexing work Base metals such as nickel silicon thermocouple.

3, add the thermocouple on the poles yttrium metal and magnesium elements, such as oxidation resistance can be further improved, the highest temperature can reach 1300 ℃.

4, K type thermocouple in order to give full play to the advantages of metal prices cheaper, at the same temperature, it can be installed more than several thermocouple, using its high sensitivity and thermoelectric properties of approximate linear characteristic, achieve the purpose of accurate measurement.

5, high measurement precision. Because of thermocouple direct contact with the object being measured, not affected by intermediate medium.

6, K type thermocouple simple structure, easy to use. Thermocouple is usually composed of two different kinds of metal wire, but is not limited by the size and the beginning of, outside has protective casing, which are very convenient.
