The conductor materials in base metal thermocouples are made of common and inexpensive metals such as Nickel, Copper and Iron. Type E: The Type E thermocouple has a Chromel (Nickel-10% Chromium) positive leg and a Constantan (Nickel- 45% Copper) negative leg.
Key Features
High EMF output, providing better sensitivity
Excellent accuracy and stability
Suitable for low to medium temperature ranges
Non-magnetic material construction
Good performance in oxidizing and cryogenic environments
Fast response due to Chromel–Constantan combination
