What is a temperature controller?
In simple terms, a temperature controller is a device used to maintain the temperature at a desired set point. It does this by constantly comparing the current temperature measured by a temperature sensor to the set temperature, thereby regulating heating or cooling to achieve the set temperature.
How does the temperature controllers work?
The working process of a temperature controller is divided into the following 5 steps:
- Temperature measurement: The temperature controller receives real-time temperature data from a temperature sensor (such as a thermocouple or RTD) placed in the monitored environment or material.
- Comparison with set point: The controller compares the measured temperature with the predefined set point (the desired temperature value). This comparison determines the temperature error, which is the difference between the current temperature and the set point.
- Control algorithm: Based on the temperature error, the controller applies the control algorithm to determine the appropriate action.
- Actuation: The controller sends a signal to the actuator (such as a heater, cooler, or valve) to adjust the heating or cooling output. For example, if the measured temperature is below the set point, the controller may increase the heating power; if it is above the set point, it may reduce the cooling.
- Feedback loop: This process is continuous, and the controller constantly receives updated temperature data, compares it to the set point, and makes adjustments as needed to maintain stable temperature control.
Temperature controllers types
A full temperature control system typically consists of three main components: a temperature sensor, a temperature controller, and an actuator.
Each component plays a distinct role in the system. The temperature sensor measures the ambient or material temperature and sends this data to the temperature controller. The controller acts as the “brain” of the system, analyzing the temperature data and determining when and how the actuator should respond to maintain the desired temperature.
There are two primary types of temperature sensors: thermocouples and resistance temperature detectors (RTDs). Thermocouples, such as types S, R, B, N, K, E, J, and T, are widely used for their simplicity and cost-effectiveness. RTDs, including models like PT100, PT1000, and Cu50, offer higher accuracy and stability, making them suitable for precision applications.
Temperature controllers can be categorized into three types based on their control accuracy: on-off controllers, proportional controllers, and PID controllers. Their precision increases in this order.
On-Off temperature controller:
On-off temperature controller is the simplest type of temperature controller, operating in two states: fully on or fully off. When the measured temperature exceeds the setpoint, the controller turns off completely; when the temperature drops below the setpoint, it turns on fully. This binary operation can result in significant temperature fluctuations and is therefore only suitable for systems that do not require precise control, such as HVAC systems, fridge and freezer, deep fryers, bread bakers, etc.
Proportional temperature controller:
A proportional controller adjusts its output in proportion to the temperature error (the difference between the measured temperature and the setpoint). If the temperature is far from the setpoint, the controller makes larger adjustments; if the temperature is close to the setpoint, it makes smaller adjustments. This proportional response helps maintain the temperature within a narrow range around the desired setpoint, offering better precision than on-off controllers but less than PID controllers.
PID temperature controller
The PID temperature controller is the most precise of the three, leveraging a Proportional-Integral-Derivative algorithm. By continuously calculating the error between the setpoint and the measured temperature, the controller fine-tunes its output to minimize this error. Over time, the measured temperature converges toward the setpoint, achieving optimal stability and accuracy. This advanced control method is ideal for applications requiring high precision and minimal temperature deviation.
Is a thermostat a temperature controller?
A thermostat is a temperature controller that uses the simple on/off control method described earlier to control temperature, and is mainly used in residential heating and cooling systems, water heaters, fridge, freezer etc.
But in most cases, the temperature controller refers to the PID temperature controller, which can control the temperature more accurately via the PID control algorithm. The PID temperature controller is used more widely in temperature process control fields, such as plastic manufacturing.
In the next section, you can get more usage scenarios of the temperature controllers.
