Temperature Measuring Instruments for Molten Metal

Temperature Measuring Instruments for Molten Metal

Smart Port is a Series of immersion type temperature measurement equipments designed for molten metals. It consist of a special electronic hardware and SMART LOGIC software which automatically corrects errors introduced due to de-rating/ageing effect of electronic components, in turn ensures long-term consistency in accuracy of measurement. Plateau Detection Technique is used for accurate molten metal temperature measurement. The microprocessor controlled electronics is housed in sturdy enclosure to suit foundry/steel plant conditions. Separate models are available for ferrous and Non-ferrous molten metal temperature measurement.


Plateau detection technique:
In this technique transient response of sensor and system is ignored. Steady state response is monitored and confirmed by taking several samples. Once it fits in its detection criteria the temperature is displayed. The operator can remove the lance to prevent it from melting in the molten metal bath. This technique displays correct temperature and ignores incorrect readings by giving error messages. Thus there is no possibility of hot spot measurement in this technique. This operation is completed in 1-3 sec in case of single dip paper tube thermocouple tips and 3-8 sec in case of Multi dip thermocouple tips. It ensures life of receptacle (connector for tip and lance). This technique is world wide used in Induction furnaces.
