Product Description

 

Chromel Alumel type K thermocouple alloy wire for sensors

Thermocouple wire or extension grade wire is recommended to be used to connect thermocouples to the sensing or control instrumentation. The conditions of measurement determine the type of thermocouple wire and insulation to be used. 


Temperature range, environment, insulation requirements, response, and service life should be considered. 


TYPE K (CHROMEL vs ALUMEL ) is used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures. 

TYPE T (Copper vs Constantan) is used or service in oxidizing, inert or reducing atmospheres or in vacuum. It is highly resistant to corrosion from atmospheric moisture and condensation and exhibits high stability at low temperatures. It is the only type with limits of error guaranteed for cryogenic temperatures.

TYPE E (CHROMEL vs Constantan) may be used in oxidizing, inert or dry reducing atmospheres, or for short periods of time under vacuum. Must be protected from sulfurous and marginally oxidizingatmospheres. Produces the highest EMF per degree o any standardized thermocouple. 


Type N thermocouple (Ni Cr Si-Ni Si Mg)  is the latest base metal thermocouple, developed to improve the drawbacks that type K thermocouple has. Type N thermocouple also be used in the similar atmospheres that type K works, and the operating temperature range is -200~1300 ℃.
