There are two fundamental types of temperature control; open loop and closed loop control. Open loop is the most basic form and applies continuous heating/cooling with no regard for the actual temperature output. It is analogous to the internal heating system in a car. On a cold day, you may need to turn the heat on to full to warm the car to 75°.
Temperature measuring and controlling module for microcontroller experiment. Temperature control is a process in which change of temperature of a space (and objects collectively there within), or of a substance, is measured or otherwise detected, and the passage of heat energy into or out of the space or substance is adjusted to achieve a desired temperature.

A Temperature Controller is a device that is used to control a heater or other equipment by comparing a sensor signal with a set point and performing calculations according to the deviation between those values. Devices that can handle sensor signals other than for temperature, such as humidity, pressure, and flow rate, are called Controllers.
Introduction to Temperature Control. 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 ...
May 5, 2022 · Temperature Control. Temperature control is very important to the application of process safety since it can prevent runaway reactions, fires and explosions, and equipment failure. Process temperature is often monitored by temperature control systems that are in place to achieve and maintain a setpoint temperature.
Mar 11, 2023 · Exothermic Reactor Temperature Control Loops. In an exothermic reaction, energy is released in the form of heat. In some cases, a cooling system is require to bring the temperature back to a set point and also to ensure that the temperature does not rapidly increase, or runaway.
Temperature Controller Current Source: One key section of a temperature controller is the Adjustable, Bi-directional Current Source. It can also be known as the Output Stage. This section responds to the Control System section by driving current to the temperature actuator (thermoelectric or resistive heater).
