A thermocouple is integrated with a temperature controller to facilitate precise temperature monitoring and control. The thermocouple's sensing end is connected to the input port of the temperature controller, typically using plugs or terminal blocks. It transmits small voltage signals generated by temperature changes to the controller, which interprets these signals into readable temperature values. The temperature controller may include calibration features to ensure accuracy based on the thermocouple's characteristics and environmental conditions. Using the temperature data from the thermocouple, the controller executes control actions such as adjusting heating or cooling devices to maintain the desired temperature set by the user. Continuous monitoring and feedback mechanisms enable the temperature controller to effectively stabilize the system within the specified temperature range.
