The enlarged cold ends of the heating elements give them the name of Dumbbell Shaped Silicon Carbide Heating Elements. The cold ends of the elements lower down the electrical resistance and helps in increasing the cold end cross section that is turn lowers the cold end operating temperature.
In the modern dumbbell alpha rods, the advanced technology is used for keeping the ends of the terminals cool, thus the over sized cold ends are no longer required.
Old style resistance ratio was 1:3.
New resistance ratio is 1:40
Maximum temperature is 1550 deg. C
