Type K thermocouples are a popular and widely used temperature measurement device.
Explanation:-
Type K Thermocouple:- Consists of two dissimilar metals: Chromel (Nickel-Chromium alloy) and Alumel (Nickel-Aluminum alloy)-
Temperature range: -200°C to 1260°C (-330°F to 2300°F)-
Sensitivity: 41 μV/°C (220 μV/°F)-
Accuracy: ±0.5% to ±1.5% (depending on the application)-
Response time: Fast ( milliseconds)-
Environment: Can withstand high temperatures, oxidation, and corrosion
Advantages:-
*Wide temperature range-
*High accuracy and sensitivity-
*Fast response time-
*Rugged and durable-
*Inexpensive compared to other thermocouple types
Common applications:-
Industrial processes (e.g., heat treatment, chemical processing)- Power generation (e.g., boilers, turbines)-
Aerospace and defense- Automotive (e.g., engine monitoring, exhaust gas temperature)
Limitations:- Not suitable for high-vacuum or reducing atmospheres- Can be affected by electromagnetic interference (EMI)
