What are the different types of thermocouples?
1. Type K (Chromel-Alumel)
Materials: Chromel (Nickel-Chromium alloy) and Alumel (Nickel-Aluminum alloy).
Temperature Range: -270°C to 1372°C (-454°F to 2502°F).
2. Type J (Iron-Constantan)
Materials: Iron (Fe) and Constantan (Copper-Nickel alloy).
Temperature Range: -40°C to 750°C (-40°F to 1382°F).
3. Type T (Copper-Constantan)
Materials: Copper (Cu) and Constantan (Copper-Nickel alloy).
Temperature Range: -200°C to 350°C (-328°F to 662°F).
4. Type E (Chromel-Constantan)
Materials: Chromel (Nickel-Chromium alloy) and Constantan (Copper-Nickel alloy).
Temperature Range: -200°C to 900°C (-328°F to 1652°F).
5. Type N (Nicrosil-Nisil)
Materials: Nicrosil (Nickel-Chromium-Silicon alloy) and Nisil (Nickel-Silicon alloy).
Temperature Range: -200°C to 1300°C (-328°F to 2372°F).
6. Type S (Platinum-Rhodium)
Materials: Platinum (Pt) and Rhodium (Rh).
Temperature Range: 0°C to 1600°C (32°F to 2912°F).
Choosing the right type of thermocouple depends on the specific temperature range, sensitivity, and application requirements. Each type offers a balance between accuracy, cost, and temperature range suitability, so it's important to match the thermocouple's specifications to the needs of your project.
