Type K Thermocouple (Chromel/Alumel) Bare Wire for Industrial Temperature Measurement
Type K thermocouples usually work in most applications as they are nickel based and exhibit good corrosion resistance. It is the most common sensor calibration type providing the widest operating temperature range. Due to its reliability and accuracy the Type K thermocouple is used extensively at temperatures up to 2300°F (1260°C).
The simplest thermocouple is made using a bare wire configuration, that is two thermoelements joined at one end and directly exposed to the atmosphere of the operating environment.
Thermocouple alloy wire(high temperature level) types , this type of thermocouple wire is mainly suitable
for thermocouple type K, J, E, T, N and L and other high temperature detection instrument, temperature sensor, etc.
