Brainchild C62 Temperature Controller

The new generation low cost PID microprocessor-based with Fuzzy logic controller series incorporate two bright easy to read LCD Displays which indicates Process value (PV) and Set point value (SP). The Fuzzy Logic technology incorporated on this series controllers enables a process to reach the predetermined set point in the shortest time with minimum of overshoot during Start up (Power ON) or external load disturbances.

Temperature control on the mold temperature machine, indirectly adjusting the temperature of the mold by adjusting the temperature of the hot fluid, can improve the production efficiency of the product and reduce the generation of defective products.

Vacuum furnace equipment / vacuum melting / vacuum heat treatment

A new algorithm for PID adjustment using fuzzy rules is used to adjust the PID algorithm to eliminate the PID saturation integral phenomenon when the error is large. When the error is small, the improved PID algorithm is used for adjustment and can be automatically adjusted. Learn and memorize some of the characteristics of the controlled object to optimize the effect

The temperature control of the electric heating cloth package is often used for the heating of the exhaust pipe valve parts of the semiconductor factory, the panel factory, or the special steel cylinder.
