Key Features
Conductor Material: The positive conductor is made from Chromel (Nickel-Chromium), and the negative conductor from Alumel (Nickel-Aluminum).
Wide Temperature Range: Suitable for measuring temperatures from approximately -270°C to 1372°C, covering cryogenic to high-temperature applications.
Good Oxidation Resistance: The NiCr/NiAl alloy is stable in oxidizing and inert atmospheres, enhancing sensor life in these conditions.
Linearity: The relationship between temperature and thermoelectric potential is nearly linear, simplifying temperature-to-voltage conversions.
Availability & Cost-Effectiveness: K-type thermocouples are the most widely used, making them readily available and relatively affordable.
Robustness: They are durable and can perform well in rough industrial environments with minimal performance loss.
