To monitor the cooling rate through the quenching process, it is necessary to precisely measure the aluminium temperature at each end of the process. This ensures the aluminium product has the required physical properties and precise dimension tolerances by the time it leaves the process. The new Spot AL LT (Low Temp) version is ideal for low-temperature quenching in aluminium extrusion and delivers market-leading readings from 130 °C (266 °F), depending on surface emissivity. A new liquid (L) temperature measurement mode for the Spot AL is also being launched. Designed specifically for temperature measurement control of liquid aluminium during melting and pouring – an important element in ensuring high-quality casting operations – this pyrometer mode delivers highly accurate results of liquid aluminium, ensuring process efficiency and high-quality castings.
In addition to the new enhancements, the Spot AL already offers dedicated pre-set algorithms to provide the most accurate digital temperature readings of low and variable emissivity aluminium in extrusion, quench, strip, forming / forging, including applications with high magnesium alloys. The Spot AL ensures optimized press speed and high-quality products with minimal scrap.
