• What is a PID temperature controller ? Jan 21 , 2022
    PID Temperature controller is a device working based on an algorithm where the controller compares the difference between the setting value and process value, based on the difference, the controller will calculate how much power needs to be feeded to the load to keep the process value as close as it can be torwards the setting value, this is a baisc concepts of the temperature controllers.
  • What is PID control and how is it different from ON/OFF control Apr 02 , 2022
    PID control is the mainstream control method that is required in a lot of industrials, like food processing, plastic extrusion, semi-conductors etc. these industrial often need precision control and overshoot should be limited, PID control is also referred to as “Three-term” control. The three terms are: P for ProportionalI for IntegralD for Derivative The output of the controller is the sum of the three factors above, PID control takes different varibles into consideration and calculate an optimized outputs to excecute and dispatch approriate power to the load, therefore controls the process by maintaing the process value as close as it can be to the setting value. ON/OFF control, is a very simple control method, in a reverse control situation, when process value is lower than the setting value, full power will be applied to the load which is ON status, when process value is higher than the setting value, 0% power will be applied and this is OFF status, if you picture a co...
