2.5 FD (E2)
The FD (E2) chamber gives the possibility to heat up the chamber to a maximum temperature of 300°C.
The measuring of the temperature will be realized by a PT100 temperature probe which is placed directly
in the inner of the chamber .
The controller R3 measures the resistance of the PT100 temperature probe and compares the incoming
signal with the actual engaged value and decides to give a Signal to activate the heating elements or not.
