Thermocouple is made of what material

Thermocouple material is used for production of thermocouple temperature measurement components. Mainly for the metal materials, non-metallic materials, such as graphite. Widespread use of thermocouple is platinum rhodium/platinum thermocouple, nickel chromium/nickel silicon ( Aluminum) Thermocouple, nickel chromium/constantan thermocouple, iron/constantan thermocouple and copper constantan thermocouple, etc.

thermocouple temperature measuring instrument is commonly used in temperature measuring element, and it is directly measured temperature, and the temperature signals into a thermoelectric emfs, through electrical instrument ( Secondary instrument) Convert the temperature of the measured medium. The appearance of all kinds of thermocouple is often due to the need to vary, but their basic structure is roughly same, usually by the hot electrode, insulation sleeve to protect the main parts such as pipe and connection box, and usually display meter, recording meter and electronic regulator.

here are all kinds of thermocouple of all kinds of materials to

S type thermocouple; Platinum rhodium - 10 Platinum thermocouple,

R type thermocouple; Platinum rhodium - 13 Platinum thermocouple

B type thermocouple. Platinum rhodium - 30 Platinum rhodium thermocouple 6

K type thermocouple; Nickel chrome - Nickel silicon thermocouple

N type thermocouple. Nickel chromium silicon - Nickel silicon thermocouple

E type thermocouple; Nickel chrome - Copper and nickel thermocouple

J type thermocouple; Iron - Copper and nickel thermocouple

T thermocouple; Copper - Copper and nickel thermocouple
