Explosion Proof Type Pyrometer

This classification includes pyrometers designed for blast furnace equipped with explosion proof instrument.

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.

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 workload. 

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.
