What is the distinguishing feature of K type thermocouple?

What is the distinguishing feature of K type thermocouple? A, detection (

Measurement) Component thermocouple is one of the industry commonly used temperature detecting element. Must go together with secondary instrument, its features are: 1. Wide measuring range. The commonly used thermocouple from - 50 ~ + 1600 ℃ are measured in succession, some special thermocouple to - can be obtained 269℃（ Such as gold iron nickel chrome) , can be up to + 2800 ℃ ( Such as tungsten - Rhenium) 。 2. High precision measurement. Because of thermocouple indirect contact with the object being measured, is not affected by two medium. 3. Easy structure, convenient use. Thermocouple is usually made up of two different kinds of metal wire, and free from all bondage of size and finish, of outer casing, maintenance is very convenient to use. Second, according to the field of temperature measurement and accuracy, choose to develop degree of thermocouple. Using the temperature at 1300 ~ 1800 ℃, the request precision is high, and compare common choose B type thermocouple; Under 1000 ℃ average with K type thermocouple and N type thermocouple, below 400 ℃ average E type thermocouple; The request precision is not high, the temperature and allow agreed to the use of tungsten-rhenium thermocouples, higher than 1800 ℃ average choose tungsten-rhenium thermocouples; Using the temperature at 1000 ~ 1300 ℃ accuracy request high availability and compare the S type thermocouple and N type thermocouple; Under 250 ℃ and negative common use T thermocouple temperature measurement, in T thermocouple stable at high temperature and high precision.
