Temperature Controllers for Sale
More About Our Selection of Temperature Controllers
All HVAC systems require control systems to monitor the operation cycle of the system. Temperature controllers are a type of control system commonly found in thermostats. They sense the actual temperature of the environment and compare that with a targeted state.
How Are Temperature Controllers Used?
In HVAC systems, temperature controllers take inputs from a temperature sensor. The sensor is usually a bimetallic disk or coil that emits an output signal to control an external feature. This external feature can be a heater, cooler, or a fan which responds to the temperature controller to raise or lower the temperature.
What Types of Temperature Controllers Are Available?
Like all control systems, temperature controllers are found in a variety of industries. In HVAC systems, they ensure the safe and efficient operation of inner components. Based on their design, they can be sorted into four categories, which are micro, proportional, on-off, and digital.
As their name suggests, micro-controllers' miniature design helps them fit into tight environments to monitor temperatures. They are easy to install on an existing circuit and require no additional controls to function.
Unlike the microcontroller, the proportional temperature controller is bigger. It operates at various time intervals. Some proportional controllers come with preset times, such as every one or two hours, while others allow users to set their own time intervals based on their needs.
On-off controllers are simpler than proportional controllers. They offer limited control and do not contain any interval settings. Their primary control is the on-off switch. Once the controller receives a temperature input, it turns the system on until the environment reaches that same temperature input before shutting off.
Digital temperature controllers contain modern technology and are the most precise. They must be tuned based on standard conditions before they can be used. However, some digital controllers tune themselves, and most can measure and control the external temperature to within 1 degree.

Key Features to Consider When Choosing a Temperature Controller
Display: Choose a controller with a dual display window that can display measured temperature and set temperature simultaneously.
Sensor Type: Make sure the controller is compatible with the temperature sensor you are using, whether it's a thermocouple, RTD, or other type of sensor.
Control Output: Depending on your heating or cooling equipment, you may need a controller with a specific type of output, such as relay, analog, or digital.
Temperature Range: Make sure the controller can handle the temperature range required for your application.
Accuracy: Choose a controller with high accuracy to ensure precise control of your residential & commercial heating or cooling process.
How to Choose the Right Temperature Controller for Your Needs
To choose the right temperature controller for your needs, consider the following factors:
Application: Determine the specific requirements of your application. Do you need to control the temperature of refrigeration equipment, heating equipment, or both?
Temperature Range: Determine the temperature range you need to control. Make sure the controller you choose can handle this range.
Control Output: Determine the type of output required to control your heating or cooling equipment.
Sensor Type: Determine the type of temperature sensor you will be using.
Additional Features: Consider any additional features you may need, such as programmability, multiple inputs and outputs, or remote monitoring and control.
