Furnace use infrared pyrometer non explosion proof

Furnace use Infrared Pyrometer non explosion proof

1. Furnace measurement usually use the traditional thercouple thermometry to implement temperature measurement in furnace (hot blast furnace, sintering furnace, heating furnace, secondary combustion chamber, Klaus furnace, etc.) . This method measure central temperature in the furnace indirectly by measuring the temperature near insulation wall with fabricated platinum rhodium-platinum thermocouple or double platinum rhodium thermocouple. Our Temperature Measurment Infrared Pyrometer specially designed by our company for the temperature measurement of hot blast stove vault can replace the thermocouple temperature measurement method to avoid many disadvantages brought by this method. The user's use results show that the device is stable, reliable and has good effect.

2.  Furnace conditions are always tough alone with high temperature and high pressure. impose restrictions on the requirements of operation environment and instrument’s structure, thermocouple thermometry would result in inaccurate measurement and lag reaction when works in strict condition such as frequently temperature changes, large pressure fluctuations and event in vibration. two color pyrometer is to measure the ratio of two specific bands of objects, when the occurrence of gray layer, water and gas, hash environmental conditions, the measured value is not affected.Implement do Accuracy Pyrometer temperature measurement.

3.  Because a thermocouple works on the condition of high temperature ( usually 1200 ℃ ~ 1300 ℃) in furnace for long term, the thermocouple terminal box also works at high temperature between 100 ℃ to 120 ℃, which will dramatically decrease instrument’s service life to a range from few weeks to few months. It will increases use-cost and maintenance workload. Infrared Thermometer compared to thermocouple, more high temperature resistance, long service life.

4.  In order to overcome above shortcomings, our company technical team  has designed and produced a serials of specialized non-Explosion Proof Type Pyrometer to ensure our infrared temperature measuring system works reliably in complex environment.

5. Infrared Pyrometer is also widely used in metallurgical cellar furnace, glass furnace, coke oven temperature measurement applications.Industrial Pyrometer has the characteristics of intuitionistic, sensitive, accurate and stable measurement, and can be used for long-distance and dynamic measurement, so it has a broad development prospect in furnace temperature measurement.
