What are Industrial Temperature Controllers? Types of .

As the name implies, a temperature controller is an instrument used to control temperatures, mainly without extensive operator involvement. A controller in a temperature control system will accept a temperature sensor such as a thermocouple or RTD as input and compare the actual temperature to the desired control temperature, or setpoint.

Checklist for Batch Reactor Temperature Control

Tight reactor temperature control enables the optimization of capacity and yield. What happens upfront in the reaction sets the stage for downstream processing and what ultimately ends up in the final product. Generally, increasing reactor temperature will increase reaction rate (capacity) but if the temperature is too high, side reactions may develop reducing reaction selectivity (yield .

Loop tuning basics: Integrating processes By James Beall. The two most common categories of process responses in industrial manufacturing processes are self-regulating and integrating.A self-regulating process response to a step input change is characterized by a change of the process variable, which moves to and stabilizes (or self-regulates) at a new value.
