Dual wavelength pyrometer device furnace use

    This pyrometer is a two color explosion proof type pyrometer, it belongs to our Industrial Pyrometer (furance use pyrometer) series. Model BFS-STRONG-SR-6018 is mid temperature 2-color pyrometer, we also provide customized service for different temperature range accodrding to application.

    1. This Infrared Pyrometer/Infrared Thermometer is Fixed Pyrometer applied to measure high temperature objects in heating furnace or hot air furnace. It is a Accuracy Pyrometer equipped with explosion proof, 2-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected.

  2. Thermocouple thermometry is the most traditionally method to detect temperature in furnaces (hot blast furnace, sintering furnace, heating furnace, secondary combustion chamber, Klaus furnace, etc.) . This methodmeasure central temperature in the furnace indirectly by measuring the temperature near insulation wall with fabricated platinum rhodium-platinum thermocouple or double platinum rhodium thermocouple.

    3. Conditions in furnace are always tough alone with high temperature and high pressure. Limited to the requirements of operation environment and instrument’s structure, thermocouple thermometry would result in inaccurate measurement and lag reaction when works in harsh condition such as frequently temperature changes, large pressure fluctuations and event in vibration.

    4. Since a thermocouple works at the high temperature ( usually 1200 ℃ ~ 1300 ℃) in furnace for long term, the thermocouple junction box also works at high temperature between 100 ℃ to 120 ℃, which will dramatically reduce instrument’s service life to a range from few weeks to few months. It will increases use-cost and maintenance workloade.

    5. In order to overcome above shortcomings, our company has designed and produced a serials of specialized infrared temperature measure device to ensure our infrared temperature measuring system works reliably in complex environment.
