Infrared thermometer SD

without displayindustrialhigh-precision

The application-specific Stove Dome (SD) system uses AMETEK Land’s advanced infrared radiation thermometer technology to monitor refractory temperatures around the stove dome or hot blast main. Using a highly accurate, and high pressure rated sighting assembly, the innovative non-contact measurement means the SD system avoids maintenance problems and slow response speeds associated with using traditional thermocouples - so there’s no need for regular, expensive equipment replacement, or for multiple thermocouples to counter the high loss rate. Installed on top or on the side of the stove, the thermometer sights onto the internal refractory checker or bridge brick-work, using a selected wavelength to ignore combustion products and ensure process efficiency. The efficiency of the recuperators is dependent on the "health" of the refractory checker work. Accurate and rapid response temperature measurement prevents possible glazing of the refractories. Sudden pressure relief in the stove can chill thermocouples by 20 to 30 degrees Celsius making their readings unreliable for approximately 30 seconds. The Land non-contact stove dome system avoids these problems by measuring the refractory surface temperature, not the gases. As a result, the Land stove dome system is much better suited for automatic changeover control, SD system provides this vital measurement for stove dome operators in Iron production. APPLICATION-SPECIFIC MOUNTING SD system has a specialised mounting arrangement designed specifically for temperature measurements in the stove dome and hot blast main.
