DESCRIPTION
2.9 Furnace temperature control
•
The Digital Temperature Controller provides master/slave or independent zone
control. It features proportional, integral and derivative (PID) temperature control
functions.
•
Digital Temperature Controller, with 3 to 5 zone spike (optional) and paddle control
per tube. Ramping, limit alarms, TC break and power failure alarms and 4
temperature recipes.
•
Thermal flatzone is depending on the type of furnace.
•
Double spike thermocouples, one for temperature control and one for the Excess
Temperature protection.
•
Tripple thermocouples, two are for the spike control (in case of failure of one) and
the third one is for the Excess Temperature protection.
•
Optional other control system, see separate manuals.
•
Thermocouple connections on source or load side of the furnace, for Paddle control
and profiling. See Figure 2-7 and Figure 2-8:
