（DXN型实体热电偶是热电偶）是热电偶生产技术的突破,其中DXN-1150型实体热电偶可以真正实现廉金属热电偶长期(有效使用1000小时以上)使用温度达到1300℃。 The thermocouple replacement product, the flame channel thermocouple (DXN type solid thermocouple is a thermocouple) is a breakthrough in the production technology of thermocouples. Among them, the DXN-1150 type solid thermocouple can truly achieve the long-term use of cheap metal thermocouples (effective use of more than 1000 hours). The temperature reached 1300 ° C. Because this new type of solid thermocouple-fireway thermocouple has a long service life and excellent stability, it will have a very wide range of applications in the temperature range of 1100-1300 ° C and has been put on the market in batches. zzyfwh.com
Fireway Thermocouple Product Technical Description
DXN-1150 type solid N thermocouple has excellent stability, reliability and long service life. It is an ideal thermocouple for automatic control system of combustion of gas anode baking furnace at this stage. In the specific use process, the following matters should be noted:
1. This thermocouple is an N-division, class II tolerance tolerance temperature measurement product.
2. Long-term use within the range of 0-1300 ℃, the limit use temperature: 1340 ℃.
3. Total length of thermocouple: 1200mm, insertion depth: 1150mm. Outer diameter:? 6mm or more.
4. Handle with care during transportation, installation, and dismantling. Do not drop by force or force straightening.
5. During calibration, the hot end of the standard thermocouple is relatively backward by 20mm.
属于温度计量产品，有精度等级要求。 6. Fire channel thermocouples are temperature measurement products and have accuracy grade requirements. Especially in the range of the process temperature use section, the temperature measurement accuracy must be achieved before it can be used.
7. The accuracy of the thermocouple will change after a period of actual use. It is recommended that the thermocouple be spot-checked every 2-3 months. If the accuracy is not reached, it should be replaced.
8. It is recommended not to use it above 1300 ℃. If the short-term temperature exceeds 1340 ℃ due to the failure of automatic control, the entire thermocouple must be replaced even if it is not melted and disconnected.
9. When the thermocouple is nearing its service life, there will be problems such as signal disconnection, large fluctuations in the signal, or a particularly low display temperature. At this time, the thermocouple should be replaced as a whole.
10. Due to the combustion system with automatic flame temperature control, it is not that the temperature on the display screens are almost the same, it is considered that the thermocouple is no problem. If the thermocouples are not regularly spot-checked, the actual temperature in the fire tunnel may be several dozen degrees higher or lower than the displayed temperature.
即可用于火道测温，也可用于料箱碳块测温。 11, the fire channel thermocouple can be used for fire channel temperature measurement, can also be used for material box carbon block temperature measurement. When used to measure the temperature of the carbon block in the bin, model: TQW-1550-6KNG,
12. Can be used in cathode baking furnace at 1280-1320 ℃.
