Overview
Industrial thermocouple assembly as a temperature sensor, usually used with display instruments, recording instruments and electronic regulators can be directly measured in a variety of production from 0 ℃ to 1800 ℃ range of liquid vapor and gas media and solid surface temperature.
In accordance with national regulations, we produce platinum thermocouples of platinum rhodium 30-platinum rhodium 6, platinum rhodium 10-platinum, nickel chrome-nickel silicon, nickel chromium-constantan, etc. in accordance with IEC international standard graduation numbers.
Assembly thermocouples are usually composed of temperature sensing elements, mounting fixtures, and junction boxes.
Measuring range and allowable error range
| Thermocouple category | Code | Division number | Measuring range | Basic error limits |
| Nickel chromium - constantan | WRK | E | 0 to 800 ° C | ± 0.75% t |
| Nickel chromium - nickel silicon | WRN | K | 0 to 1300 ° C | ± 0.75% t |
| Platinum Rhodium 13 - Platinum | WRB | R | 0-1600 ° C | ± 0.25% t |
| Platinum Rhodium 10 - Platinum | WRP | S | 0 to 1600 ° C | ± 0.25% t |
| Platinum Rhodium 30 - Platinum Rhodium 6 | WRR | B | 0 to 1800 ° C | ± 0.25% t |
Note: t for the temperature sensing element measured temperature (℃)
Thermocouple time constant
| Thermal inertness level | Time constant (seconds) | Thermal inertness level | Time constant (seconds) |
| I | 90- 180 | III | 10- 30 |
| II | 30- 90 | IV | < 10 |
Thermocouple nominal pressure: generally refers to the working temperature of the protection tube can withstand static external pressure and rupture.
The minimum insertion depth of the thermocouple shall be not less than 8 to 10 times the outer diameter of the protective sleeve (except for the special column product)
Insulation resistance: When the ambient air temperature is 15-35 ℃, relative humidity< 80% 时绝缘电阻≥5兆欧 (电压100V) . 具有防溅式接线盒的热电偶, 当相对温度为93± 3℃ 时, 绝缘电阻≥0.5兆欧 (电压100V)
Insulation Resistance at High Temperature: The insulation resistance (in meters per meter) between the thermocouple (including the double support) and the protective tube and the double support thermocouple shall be greater than the values specified in the table below at high temperatures.
| The specified long-term use temperature (℃) | Test temperature (℃) | Insulation Resistance (Ω) |
| Gt; | 600 | 72000 |
| ≥ 800 | 800 | 25000 |
| ≥1000 | 1000 | 5000 |
