Brainchild C62 Low-cost Process and Temperature Controllers

Brainchild C62 Low-cost Process and Temperature Controllers, The proportional integral derivative (PID) controllers are the most widely used control strategy in the industry due to they can operate the majority of the control system in the world. It has been reported that more than 95% of the controllers in the industrial process control applications are of PID type as no other controller matches the simplicity, clear functionality, applicability, and ease of use offered by the PID controller.

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