Digital PID temperature controller: your ultimate guide
In the temperature control system, the digital temperature controller is a key component that cannot be ignored. But what exactly is it and how to choose the right digital thermostat, etc., we will provide you with the ultimate guide.
What is the digital PID temperature controller?
A digital PID temperature controller is a process instrument used to monitor and control temperature to achieve and maintain a set point. Digital PID temperature controllers are often used with solid state relays, AC contactors, or Контроллеры питания SCR to provide heating via heaters or cooling via compressors.
How many types of the digital temperature controller?
There are many types of temperature controllers available in the market, such as Bang-Bang controllers (on/off temperature controllers), proportional temperature controllers, PID temperature controllers, programmable temperature controllers (also known as multi-loop temperature controllers or ramp and soak temperature controllers). For more information, you can have a look at our article: Temperature Controller Types: A Comprehensive Guide.
What is the difference between the digital PID temperature controller and thermostat?
- Точность: Digital temperature controllers use the most advanced PID algorithm to reduce the difference between the setting temperature and present temperature, while thermostat control method is Bang-bang control, thus digital temperature controllers accuracy is much higher than thermostat.
- Applications: Digital PID temperature controllers are suitable for industrial processes, laboratory equipment, medical equipment, etc. that require precise and complex control. Thermostats are mainly used in heating, ventilation, and air conditioning systems (HVAC) in homes and small commercial buildings.
- Programmable: Both digital PID temperature controllers and thermostats are temperature programmable, but the PID thermostat is more advanced and its PID (proportional-integral-derivative) parameters can be modified according to different applications, while the thermostat can only be programmed for its set temperature.
- Product cost:Digital pid temperature controllers are more expensive due to their advanced features and precise control capabilities.Thermostats are relatively low cost due to their simplicity.
8 specific steps to choose the right digital PID temperature controller
- Know your application: PID temperature controller is more suitable for heating applications, such as ovens, furnaces and controlling heater heating temperature, etc. We can also use it for cooling, but remember that the controller has this function.
- Choose the suitable output: Digital pid temperature controllers have many outputs available such as SSR, relay or analog 4-20 mA or 0-10VDC, thus how to choose it? Remember that if you want to control the heating more accurately, you had better choose the analog output, or at least SSR output, analog output can make the output more smoother than the SSR or relay PWM control. SSR or relay? Which is better? Please see our article: SSR и контактор переменного тока: Что лучше в системе контроля температуры?
- Choose input: Some economical pid temperature controllers may only have thermocouple inputs, but if you want to use it with 4-20 mA or 0-10VDC analog inputs or thermal resistors (RTDs) such as PT100 or Cu50, make sure your temperature controller supports them.
- Рабочее напряжение: Working voltage is also an important factor to consider, if you want it to work at 110VAC or 220VAC, you must use 100-240VAC wide working voltage, if there is no AC voltage available, there is only 24VDC power supply, please make sure your temperature controller can work at this voltage.
- Panel size: Digital pid temperature controllers usually have 5 panel sizes, which are 48*48mm, 48*96mm, 72*72mm, 96*48mm or 96*96mm, please make sure which panel size you need.
- Общение: Some application scenarios may require the temperature controller to have a communication function, please make sure your temperature controller has this function. Our above temperature controller has RS485 communication function, which can help you remotely monitor and set the temperature through computer, touch screen or SCADA system.
- Установка: Generally, the temperature controller can be installed through a fixed structure panel, you need to drill a suitable hole and insert it, and then fix it with a fixed structure. But some applications may often use DIN rails to make the whole system look more beautiful, please make sure your pid thermostat is installed as you require.
- Время выборки: Fast sampling means more accurate temperature control, our TCN4 new temperature controller has a sampling time as fast as 100 milliseconds, which is faster than our REX-C and CH series pid temperature controllers. So if you are not worried about the budget, please choose the fast sampling one.
