A temperature controller, as the name suggests, is a device which has been built to regulate temperature automatically. It functions by continuously monitoring the process variable (current temperature) and comparing it to the desired setpoint. The difference between these values, known as the error deviation, is used to determine the necessary amount of heating or cooling required to bring the temperature back to the desired level.
The controller generates a manipulated signal, which is the output value that directs the temperature control device to adjust the heating or cooling accordingly. This automated process ensures precise and consistent temperature regulation without the need for constant manual intervention.

PID Temperature Controller
The PID temperature controller's primary function is to measure the temperature indicated by the thermometer and compare it to the desired setpoint. It then adjusts the heater's output to maintain a constant temperature. The term "PID" stands for Proportional-Integral-Derivative, referring to the three control functions that help achieve precise temperature control:
- Proportional Control: Adjusts the heater output proportionally to the difference between the setpoint and the measured temperature.
- Integral Control: Corrects past temperature deviations by adjusting the heater output to eliminate cumulative errors over time.
- Derivative Control: Anticipates future temperature changes based on the rate of change, allowing for more responsive adjustments.
Digital Temperature Controller
A digital temperature controller is a device designed to help regulate temperature precisely. These types of temperature controllers are grouped into two categories: DTC-A series and DTC-T series.
DTC-A Series
The primary goal of the DTC-A series is to ensure precise heating without the need for external relays, as the temperature can be easily controlled internally. These controllers allow for adjustments according to time intervals and can memorize temperature settings and time. They are particularly suitable for various types of flexible heaters.
DTC-T Series
The DTC-T series of digital temperature controllers offer monitoring capabilities for both DC and AC voltages. These controllers are characterized by low electromagnetic-wave and voltage output, making them suitable for environments sensitive to electromagnetic interference.
They come equipped with adapters for better temperature settings and customized time intervals. Like the DTC-A series, the DTC-T series can also memorize temperature and time settings, eliminating the need for additional circuit design or controls. Furthermore, the DTC-T series features four power settings: 100%, 75%, 50%, and 25%, providing flexibility in power management.
