Product Description
As a sensor for measuring temperature, thermocouples are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the temperature of liquid, steam and gas media in various production processes ranging from 0ºC to 1800ºC.
- High quality temperature sensing elements, stable and reliable performance
- High mechanical strength and good pressure resistance
- Large measuring range and high measuring accuracy

Thermal response time
When there is a step change in temperature, the time required for the output of the thermal resistor to change to 50% of the step change is called the thermal response time and is represented by T0.5.| Protection tube diameter(mm) | Protective tube material | Thermal response time(s) |
| Φ16 | High aluminum tube/corundum tube | ≤150 |
| Metal tube | ≤90 | |
| Φ20 | High aluminum tube/corundum tube | ≤240 |
| Metal tube | ≤90 | |
| Φ25 | High aluminum tube/corundum tube | ≤360 |
| Tapered protective tube | Metal tube | ≤150 |
