Level measurement of molten iron
A steel company in the Dominican Republic faced challenges in measuring the level of molten iron within a measurement interval of 600 mm. In certain parts of the process, temperatures peaked at 1600°C. The high ambient temperature of 210°C posed a significant risk of burns, making manual level determination difficult and dangerous. Sensors for this application need to withstand these extreme temperatures. Many sensors have been damaged previously due to these harsh conditions.
Our ideal solution for this application involved using the high-temperature variant of the non-contact radar sensor NivoRadar NR 3000, in conjunction with the high temperature standpipe. To manage the high ambient temperatures, a cold air chamber was constructed around the radar transmitter housing, ensuring a maximum ambient temperature of 70ºC. This configuration ensures precise measurement results for molten iron even in extreme temperature conditions.
