As the name implies, a temperature controller is an instrument used to control temperatures, mainly without extensive operator involvement.
Temperature controllers are designed to maintain desired temperature levels, regardless of external conditions. Whether it needs to stay at one setpoint or exist within a range, these controllers ensure safety, reduce variability, and increase overall efficiency. Designed to fit into control panels, temperature controllers feature a number of control actions including PID, on-off, multi-loop ...
Temperature / Process Controllers Process controllers take an input signal (temperature, pressure, flow or level) and maintain a setpoint using an output (relay, voltage pulse, current or linear voltage, depending on the model). Various controllers support modes such as PID, ON/OFF, Ramp/Soak, and Manual.
These Controllers receive sensor signals and control heaters or other devices to maintain a preset temperature. They can also be used for humidity, pressure, and flowrate control. OMRON also provides temperature and humidity sensors.
