Selection of heating element

Alloys

The heating element alloys currently supported by the temperature controller are:
Type Name
0 Nickrome40®
1 Alloy20®
2 Steel AISI316
3 MS500 (it is not an alloy, but is used to adapt the air heater to the temperature
controller)
Nickrome40 and Alloy20 are registered trademarks of the relevant manufacturer.

Transformer dimensioning

Considering the voltage of the primary should be the same as the power supply voltage of the
temperature controller and then 230Vac or 115Vac, another two parameters must be defined:
voltage to the secondary and transformer power. To calculate these parameters, start with the
quantity of energy necessary for the operation, however for simplicity purposes it is considered
that to heat a bar to approx. 200°C in approx. 200mS a specific power of 30W per cm
on the outer surface of the heating element.
