Cascade Control
(Tight Box Internal Temperature Control) |
|
- Improved Temperature Increase Delay
• Better than previous single-control systems, temperature is maintained closer to the temperature of the item being treated.
• Eliminates need for offset between control temperature and temperature of item being treated.

Tight Box Internal Temperature Control
1)Tight box internal temperature data is fed back to master adjustment gauge controler.
2)Master adjustment gauge controler corrects for differences between
actual and setting temperatures.
3)Master sends correction signal to slave and slave sets temperature
to corrected value.
4)Temperature data for outside tight box (heater zone) is fed back
to slave adjustment gauge controler.
5)Correction signal for difference between temperature outside tight
box and slave setting value is output to each thyristor. |
