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.
