High Temperature Measurement Thermocouple With Fast Response And Durable Design
A thermocouple is a temperature sensor based on the thermoelectric effect. It consists of two wires made of different metal materials. When the two metals at the connection point (hot junction) are exposed to a temperature change, a thermoelectric potential (voltage) related to the temperature is generated.
The core technology in the application of thermocouples is cold junction compensation. Common methods of cold junction compensation include:
Thermocouples are usually identified by letter designation codes, and different codes have different characteristics and application ranges.
| Designation Code | Positive-Negative Materials | Approximate Temperature Range | Characteristics and Application Scenarios |
|---|---|---|---|
| K | Nickel-Chromium - Nickel-Silicon | -200°C to +1300°C | Highly common. Good cost performance, good linearity, and strong oxidation resistance. Suitable for oxidizing, neutral atmospheres. |
| J | Iron - Constantan | -40°C to +750°C | High sensitivity and low cost. Can be used in vacuum, oxidizing, and reducing atmospheres. However, iron is prone to rust. |
| T | Copper - Constantan | -200°C to +350°C | High precision and good stability, used for low-temperature measurement. Resistant to moisture corrosion. |
| E | Nickel-Chromium - Constantan | -200°C to +900°C | Has the highest thermoelectric potential (most sensitive), suitable for oxidizing and weakly reducing atmospheres. |
| N | Nickel-Chromium-Silicon - Nickel-Silicon | -200°C to +1300°C | An improved version of type K, with better high-temperature stability and oxidation resistance, and longer lifespan. |
| S | Platinum-Rhodium 10 - Platinum | 0°C to +1600°C | Precious metal thermocouple. High precision, good stability, and strong oxidation resistance. Used in high-temperature, high-precision applications, such as laboratories and metallurgy. |
| R | Platinum-Rhodium 13 - Platinum | 0°C to +1600°C | Similar to type S, with slightly higher thermoelectric potential. |
| B | Platinum-Rhodium 30 - Platinum-Rhodium 6 | 0°C to +1800°C | Has the highest temperature range among standard types. The thermoelectric potential at the cold end is extremely small when the cold end is between 0-50°C, and cold end compensation can be ignored. |
