Among them, the N-1150 type solid thermocouple can truly realize the long-term (effective use of more than 1000 hours) low-temperature thermocouples.
Product technical description
具有优异的稳定性、可靠性和较长的使用寿命，是现阶段较理想的燃气阳极焙烧炉燃烧自动控制系统用热电偶。 N-1150 type solid N- channel 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.
6. Thermocouples are temperature measurement products with 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 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.
11. The thermocouple can be used to measure the temperature in the fire tunnel, and it can also be used to measure the temperature of the carbon block in the bin. 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 ℃.
具有较长的使用寿命和优异的稳定性，将在1100-1300℃温度范围内具有非常广泛的应用，已批量投放市场。 Because of its long service life and excellent stability, this new type of solid flame thermocouple will have a wide range of applications in the temperature range of 1100-1300 ° C and has been put on the market in batches.
