Kiln Shell Scanner

الوصف

The maxim health is wealth is applicable to the cement kiln, too. As long as the shell is rotating, the level of profitability is high. Every time a kiln is stopped, a drop in revenue occurs. So the choice of the best monitoring tools providing trust indicators before serious failures occur, is essential. Millennium-TMCx™ Infrared Linescanners, ­enabling continuous surveillance of kiln shell temperature, has a central position in the control room of hundreds of modern cement plants around the world.
The "Opto-mechanical " deflrction unit of all TMCx- Sensors designed to withstand a continuous high-speed operation up to **0Hz. The speed of this scan-mirror is digitally controlled. For every **0° rotation (complete scanline) is effective scan angle or field of view ("FOV") is max **0°. During the scanning the heat radiation of the object is continuosly picked up and transferred by the scan mirror through a lens assembly to the TE-cooled infrared detector. The detector siglal is digitized by a **2 ADC at a sampling rate that results to ***2 points per complete **0° scanline independent of the actual scan speed. The resulting spot measurment information is intermediately stored into a *6 bit pixel buffer together with additional 4 bit sensoe status information and then transmitted in real time at a rate of up to *0 MHz via Gesotec integrated fiber-Optic Data-Link "DaLli-Tx" to the data- acquisition-controller "DACx" located up to 2 Km away.
