What are the different types of thermocouple?
Thermocouple Types
| Thermocouple Type | Useful/General Application Range |
|---|---|
| C* | 1650-2315°C (3000-4200°F) |
| E** | 95-900°C (200-1650°F) |
| J | 95-760°C (200-1400°F) |
| K** | 95-1260°C (200-2300°F) |
What are K type thermocouples used for?
Type K Thermocouple provides widest operating temperature range. It consist of positive leg which is non-magnetic and negative leg which is magnetic.In K Type Thermocouple traditional base metal is used due to which it can work at high temperature and can provide widest operating temperature range.
What is the material and temperature ranges of type E J K M N and T thermocouple?
Thermocouple Grade Wire
| Calibration Type | Temperature Range | |
|---|---|---|
| J | 32 to 1382°F | 0 to 750°C |
| K | 32 to 2282°F | 0 to 1250°C |
| E | 32 to 1652°F | 0 to 900°C |
| T | 32 to 662°F | 0 to 350°C |
What is Type K material?
Type K Thermocouple (Nickel-Chromium / Nickel-Alumel): The type K is the most common type of thermocouple. It’s inexpensive, accurate, reliable, and has a wide temperature range. The type K is commonly found in nuclear applications because of its relative radiation hardness.
